Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31764, here are decompositions:
- 13 + 31751 = 31764
- 23 + 31741 = 31764
- 37 + 31727 = 31764
- 41 + 31723 = 31764
- 43 + 31721 = 31764
- 97 + 31667 = 31764
- 101 + 31663 = 31764
- 107 + 31657 = 31764
Showing the first eight; more decompositions exist.
