Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545108, here are decompositions:
- 11 + 31545097 = 31545108
- 17 + 31545091 = 31545108
- 41 + 31545067 = 31545108
- 47 + 31545061 = 31545108
- 59 + 31545049 = 31545108
- 107 + 31545001 = 31545108
- 139 + 31544969 = 31545108
- 167 + 31544941 = 31545108
Showing the first eight; more decompositions exist.
