Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516646, here are decompositions:
- 13 + 31516633 = 31516646
- 19 + 31516627 = 31516646
- 43 + 31516603 = 31516646
- 79 + 31516567 = 31516646
- 103 + 31516543 = 31516646
- 127 + 31516519 = 31516646
- 163 + 31516483 = 31516646
- 223 + 31516423 = 31516646
Showing the first eight; more decompositions exist.
