How does Euler verify Goldbach's problem?

Euler, a famous mathematician, studied Goldbach's problems very seriously. Perhaps, at first, he thought it was easy to prove this question, because it was the simplest and most basic. However, it is often the simplest and most basic questions that are the most important.

To Euler's surprise, it turned out that the work was not smooth. The mathematician who has made outstanding contributions to number theory has tried his best, but it has proved that he has made no progress. He didn't even find the right evidence. Euler verified these two conjectures over and over again. Although he didn't prove them, he was convinced of their correctness by the mathematician's intuition. 1742 On June 30th, he wrote to Goldbach: I think this is a definite theorem, although I can't prove it yet.

As a natural scientist, Euler is excellent. He didn't cover up his guess because of his failure. He published Goldbach's Letter to the World.

Like Euler, the great mathematicians in the18th century opened their eyes in surprise and said with one voice: Goldbach conjecture, the jewel in the crown!

A knowledgeable math teacher in our country once introduced Goldbach's conjecture to high school students with great interest. He told his classmates that every big even number can be written as the sum of two prime numbers. This is Goldbach's conjecture, this is the jewel in the crown!

The students all opened their eyes in surprise.

The teacher said that you all know even numbers and odd numbers, and you all know prime numbers and composite numbers. We have already learned this. Isn't this the simplest? No, this problem is the most difficult, very difficult, if someone can solve it, that would be great!

Students quarreled: What's the big deal? Let's get started. We can do it. They brag about Haikou.

The teacher also smiled. He said, "Really, I had a dream last night. I dreamed that there was a classmate among you. He's amazing. He proved Goldbach's conjecture. "

High school students burst into laughter.

The next day, classes began again. Several hard-working students excitedly gave the teacher some answer sheets. They said that they succeeded, which can prove the German conjecture. "It can be proved in many ways, and it's not a big deal. Ha ha! Haha! "

"Forget it!" The teacher smiled and said, "Forget it! Forget it! "

"We forget it, forget it. We figured it out! "

"You forget it! Okay, okay, I mean, forget it. What are you wasting your energy on? I won't read any of your papers. I don't need to read them. Is it that easy? You want to go to the moon by bike. "

There was another burst of laughter in the classroom, and those students who didn't hand in their papers laughed at those who did. They laughed themselves, stamped their feet with laughter, and almost burst into laughter.

Is this problem really that difficult? Is this pearl really that hard to pick? It's really hard!

/kloc-from the 0/8th century to the 20th century, many major breakthroughs have been made in natural science, the basic theories of many disciplines have been updated, and epoch-making major inventions have emerged. Not only that, human beings are relying on the living earth to uncover the secrets of their own reproduction; The study of nuclear physics has gone deep into the nuclear energy level of quarks.

However, this simplest problem, the most basic problem, every big even number can be written as the sum of two prime numbers. Goldbach guessed that the jewel in the crown was still hanging there quietly, showing her pride and beauty to mankind.

Every big even number can be written as the sum of two prime numbers, which can be expressed in a concise and inaccurate way, namely (1+ 1). Goldbach's conjecture is (1+ 1).

For this (1+ 1), Euler, a great mathematician, spent all his energy, but by the time he finished the mileage of his life, he had not seen the dawn of (1+ 1).

/kloc-in the 8th century, after Euler announced Goldbach's conjecture, many famous mathematicians devoted themselves to research. Even a mathematician devoted his whole life to research. However, in the whole18th century, mathematicians did not produce any results in the face of (1+ 1).
