Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31732, here are decompositions:
- 3 + 31729 = 31732
- 5 + 31727 = 31732
- 11 + 31721 = 31732
- 83 + 31649 = 31732
- 89 + 31643 = 31732
- 131 + 31601 = 31732
- 149 + 31583 = 31732
- 191 + 31541 = 31732
Showing the first eight; more decompositions exist.
