Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51938, here are decompositions:
- 31 + 51907 = 51938
- 67 + 51871 = 51938
- 79 + 51859 = 51938
- 109 + 51829 = 51938
- 151 + 51787 = 51938
- 307 + 51631 = 51938
- 331 + 51607 = 51938
- 421 + 51517 = 51938
Showing the first eight; more decompositions exist.
