1960年,我看到新出版的原苏联数学家布赫夕塔布写的教科书《数论》第358页上写道:“王元在1958年成功地证明了定理347。每一个充分大的偶数2N 都可以表成 n+n’,其中 n 的素因子个数不超过2,而n’的素因于个数不超过3”(即“2+3”)。我总算为国家做出了一点贡献,激动得热泪盈眶,浮想联翩。1952年我大学毕业,被分配到中国科学院数学研究所,跟随著名数学家华罗庚先生学习并一起工作。华先生让我 In 1960 I read on page 358 of the newly published textbook “Number Theory” written by former Soviet mathematician Buhta Taubu: “Wang Yuan succeeded in proving the theorem in 1958. Each of the sufficiently large Even numbers 2N can be expressed as n + n ', where the number of prime factors of n does not exceed 2, and the prime of n' does not exceed 3 ”(ie “ 2 + 3 ”). I finally made a contribution for the country, excited tears, imagination. I graduated from college in 1952, was assigned to the Institute of Mathematics, Chinese Academy of Sciences, following the famous mathematician Hua Luogeng to learn and work together. Mr. Hua let me
