Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545662, here are decompositions:
- 163 + 31545499 = 31545662
- 193 + 31545469 = 31545662
- 223 + 31545439 = 31545662
- 271 + 31545391 = 31545662
- 283 + 31545379 = 31545662
- 331 + 31545331 = 31545662
- 571 + 31545091 = 31545662
- 601 + 31545061 = 31545662
Showing the first eight; more decompositions exist.
