Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460688, here are decompositions:
- 11 + 31460677 = 31460688
- 31 + 31460657 = 31460688
- 41 + 31460647 = 31460688
- 79 + 31460609 = 31460688
- 107 + 31460581 = 31460688
- 137 + 31460551 = 31460688
- 139 + 31460549 = 31460688
- 151 + 31460537 = 31460688
Showing the first eight; more decompositions exist.
