Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31938, here are decompositions:
- 31 + 31907 = 31938
- 47 + 31891 = 31938
- 79 + 31859 = 31938
- 89 + 31849 = 31938
- 139 + 31799 = 31938
- 167 + 31771 = 31938
- 197 + 31741 = 31938
- 211 + 31727 = 31938
Showing the first eight; more decompositions exist.
