Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545242, here are decompositions:
- 31 + 31545211 = 31545242
- 61 + 31545181 = 31545242
- 151 + 31545091 = 31545242
- 181 + 31545061 = 31545242
- 193 + 31545049 = 31545242
- 241 + 31545001 = 31545242
- 523 + 31544719 = 31545242
- 691 + 31544551 = 31545242
Showing the first eight; more decompositions exist.
