Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545394, here are decompositions:
- 3 + 31545391 = 31545394
- 71 + 31545323 = 31545394
- 107 + 31545287 = 31545394
- 173 + 31545221 = 31545394
- 311 + 31545083 = 31545394
- 431 + 31544963 = 31545394
- 677 + 31544717 = 31545394
- 821 + 31544573 = 31545394
Showing the first eight; more decompositions exist.
