Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516670, here are decompositions:
- 37 + 31516633 = 31516670
- 43 + 31516627 = 31516670
- 67 + 31516603 = 31516670
- 103 + 31516567 = 31516670
- 127 + 31516543 = 31516670
- 151 + 31516519 = 31516670
- 313 + 31516357 = 31516670
- 337 + 31516333 = 31516670
Showing the first eight; more decompositions exist.
