Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545078, here are decompositions:
- 11 + 31545067 = 31545078
- 17 + 31545061 = 31545078
- 29 + 31545049 = 31545078
- 109 + 31544969 = 31545078
- 137 + 31544941 = 31545078
- 179 + 31544899 = 31545078
- 199 + 31544879 = 31545078
- 251 + 31544827 = 31545078
Showing the first eight; more decompositions exist.
