Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516630, here are decompositions:
- 3 + 31516627 = 31516630
- 11 + 31516619 = 31516630
- 17 + 31516613 = 31516630
- 59 + 31516571 = 31516630
- 71 + 31516559 = 31516630
- 107 + 31516523 = 31516630
- 137 + 31516493 = 31516630
- 251 + 31516379 = 31516630
Showing the first eight; more decompositions exist.
