Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31656, here are decompositions:
- 7 + 31649 = 31656
- 13 + 31643 = 31656
- 29 + 31627 = 31656
- 73 + 31583 = 31656
- 83 + 31573 = 31656
- 89 + 31567 = 31656
- 109 + 31547 = 31656
- 113 + 31543 = 31656
Showing the first eight; more decompositions exist.
