How can China prove "1+ 1=2"

"1+ 1=2" refers to Goldbach's conjecture. Hua did not prove Goldbach's conjecture. China's mathematician who made great contribution to the study of Goldbach's conjecture was Chen Jingrun, 1957+00. Due to the appreciation of Professor Hua, Chen Jingrun was transferred to the Institute of Mathematics of China Academy of Sciences, 1973.

In May 20 13, Harold Horovgott, a researcher at Paris Teachers College, published two papers, announcing that the weak Goldbach conjecture was completely proved.

Extended data:

Hua was the first mathematician in China who engaged in Goldbach conjecture. From 1936 to 1938, he went to England to study, studied number theory under Hardy, and began to study Goldbach conjecture, which almost verified all even conjectures.

From 65438 to 0950, after returning from the United States, Hua organized a seminar on number theory at the Institute of Mathematics of China Academy of Sciences, and chose Goldbach conjecture as the topic of discussion. Wang Yuan, Pan Chengdong, Chen Jingrun and other students who attended the seminar made good achievements in proving Goldbach's conjecture.

1956, Wang Yuan proved "3+4"; In the same year, the mathematician A.V. Noguera Dov of the former Soviet Union proved "3+3"; 1957, Wang Yuan proved "2+3"; Pan chengdong proved "1+5" in 1962; 1963, Pan Chengdong, Barba En and Wang Yuan all proved "1+4"; 1966, Chen Jingrun proved "1+2" after making new and important improvements to the screening method.
