Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624, here are decompositions:
- 17 + 31607 = 31624
- 23 + 31601 = 31624
- 41 + 31583 = 31624
- 83 + 31541 = 31624
- 107 + 31517 = 31624
- 113 + 31511 = 31624
- 227 + 31397 = 31624
- 233 + 31391 = 31624
Showing the first eight; more decompositions exist.
