Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31750, here are decompositions:
- 23 + 31727 = 31750
- 29 + 31721 = 31750
- 83 + 31667 = 31750
- 101 + 31649 = 31750
- 107 + 31643 = 31750
- 149 + 31601 = 31750
- 167 + 31583 = 31750
- 233 + 31517 = 31750
Showing the first eight; more decompositions exist.
