Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516776, here are decompositions:
- 19 + 31516757 = 31516776
- 23 + 31516753 = 31516776
- 47 + 31516729 = 31516776
- 73 + 31516703 = 31516776
- 79 + 31516697 = 31516776
- 107 + 31516669 = 31516776
- 149 + 31516627 = 31516776
- 157 + 31516619 = 31516776
Showing the first eight; more decompositions exist.
