Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545268, here are decompositions:
- 47 + 31545221 = 31545268
- 149 + 31545119 = 31545268
- 389 + 31544879 = 31545268
- 449 + 31544819 = 31545268
- 509 + 31544759 = 31545268
- 971 + 31544297 = 31545268
- 1061 + 31544207 = 31545268
- 1097 + 31544171 = 31545268
Showing the first eight; more decompositions exist.
