Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31758, here are decompositions:
- 7 + 31751 = 31758
- 17 + 31741 = 31758
- 29 + 31729 = 31758
- 31 + 31727 = 31758
- 37 + 31721 = 31758
- 59 + 31699 = 31758
- 71 + 31687 = 31758
- 101 + 31657 = 31758
Showing the first eight; more decompositions exist.
