Why do mathematicians always study "1+ 1"?

Many people may have heard that mathematicians are still studying the problem of 1+ 1=2, and there is no result yet. But in fact, mathematicians have long confirmed the formula of 1+ 1=2, and the so-called "1+ 1=2" is actually related to Goldbach's conjecture.

/kloc-in the 8th century, the mathematician Goldbach put forward an interesting conjecture that any even number greater than 2 (that is, even number greater than or equal to 4) can be expressed as the sum of two prime numbers (some have more than one splitting method). For example, 4 = 2+2,18 = 5+13 = 7+11. It is proved that Goldbach's conjecture is called solving the problem of "1+ 1=2", and the more accurate description should be "1+ 1".

At that time, Goldbach turned to the great mathematician Euler for help, but even Euler failed to prove it. For a long time, this problem has been puzzling mathematicians of all ages, and it has not been solved so far, and it has become one of the three unsolved problems in mathematics.

So far, the closest proof to Goldbach's conjecture was obtained by Chen Jingrun, a famous mathematician in China. In 1966, Chen Jingrun proved that a large even number can be expressed as the sum of two prime numbers, or the sum of a prime number and a semi-prime number (the product of two prime numbers). Chen Jingrun's work has made a great breakthrough in the study of Goldbach's conjecture. Completed the proof of "1+2", which is called "Chen Theorem".

People admire Chen Jingrun's great achievements under difficult conditions. That year, in order to prove "1+2", Chen Jingrun worked hard and spent several sacks of draft paper. This perseverance can only be compared with others.

After Chen Jingrun, someone claimed to have proved "1+ 1". However, these so-called Goldbach conjectures proved to be untenable. Goldbach's conjecture involves very difficult mathematics, which is not as easy as most people think. Not a superb mathematician, it proves that Goldbach's conjecture is unrealistic.
