Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535724, here are decompositions:
- 7 + 31535717 = 31535724
- 43 + 31535681 = 31535724
- 53 + 31535671 = 31535724
- 67 + 31535657 = 31535724
- 131 + 31535593 = 31535724
- 173 + 31535551 = 31535724
- 257 + 31535467 = 31535724
- 307 + 31535417 = 31535724
Showing the first eight; more decompositions exist.
