Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545260, here are decompositions:
- 79 + 31545181 = 31545260
- 163 + 31545097 = 31545260
- 193 + 31545067 = 31545260
- 199 + 31545061 = 31545260
- 211 + 31545049 = 31545260
- 337 + 31544923 = 31545260
- 433 + 31544827 = 31545260
- 541 + 31544719 = 31545260
Showing the first eight; more decompositions exist.
