Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545162, here are decompositions:
- 43 + 31545119 = 31545162
- 71 + 31545091 = 31545162
- 79 + 31545083 = 31545162
- 101 + 31545061 = 31545162
- 113 + 31545049 = 31545162
- 139 + 31545023 = 31545162
- 193 + 31544969 = 31545162
- 199 + 31544963 = 31545162
Showing the first eight; more decompositions exist.
