Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545324, here are decompositions:
- 7 + 31545317 = 31545324
- 37 + 31545287 = 31545324
- 103 + 31545221 = 31545324
- 113 + 31545211 = 31545324
- 227 + 31545097 = 31545324
- 233 + 31545091 = 31545324
- 241 + 31545083 = 31545324
- 257 + 31545067 = 31545324
Showing the first eight; more decompositions exist.
