Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31756, here are decompositions:
- 5 + 31751 = 31756
- 29 + 31727 = 31756
- 89 + 31667 = 31756
- 107 + 31649 = 31756
- 113 + 31643 = 31756
- 149 + 31607 = 31756
- 173 + 31583 = 31756
- 239 + 31517 = 31756
Showing the first eight; more decompositions exist.
