Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31716, here are decompositions:
- 17 + 31699 = 31716
- 29 + 31687 = 31716
- 53 + 31663 = 31716
- 59 + 31657 = 31716
- 67 + 31649 = 31716
- 73 + 31643 = 31716
- 89 + 31627 = 31716
- 109 + 31607 = 31716
Showing the first eight; more decompositions exist.
