Pan Chengdong (Chinese: 潘承洞; pinyin: Pān Chéngdòng; 26 May 1934 – 27 December 1997) was a Chinese mathematician who made numerous contributions to number theory, including progress on Goldbach's conjecture.

[1] Born in Suzhou, Jiangsu Province on 26 May 1934, he entered the Department of Mathematics and Mechanics of Peking University in 1952[2] and obtained a postgraduate degree in 1961 advised by Min Sihe, a student of Edward Charles Titchmarsh.

[3] Previously, Wang Yuan made progress toward Goldbach’s Conjecture on the distribution of prime numbers.

In 1962, Pan Chengdong also made progress in proving Goldbach’s conjecture [4] by proving the (1,5) case independently and the (1,4) case the following year with N.B.
