Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31768, here are decompositions:
- 17 + 31751 = 31768
- 41 + 31727 = 31768
- 47 + 31721 = 31768
- 101 + 31667 = 31768
- 167 + 31601 = 31768
- 227 + 31541 = 31768
- 251 + 31517 = 31768
- 257 + 31511 = 31768
Showing the first eight; more decompositions exist.
