Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545374, here are decompositions:
- 31 + 31545343 = 31545374
- 43 + 31545331 = 31545374
- 163 + 31545211 = 31545374
- 193 + 31545181 = 31545374
- 277 + 31545097 = 31545374
- 283 + 31545091 = 31545374
- 307 + 31545067 = 31545374
- 313 + 31545061 = 31545374
Showing the first eight; more decompositions exist.
