Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31752, here are decompositions:
- 11 + 31741 = 31752
- 23 + 31729 = 31752
- 29 + 31723 = 31752
- 31 + 31721 = 31752
- 53 + 31699 = 31752
- 89 + 31663 = 31752
- 103 + 31649 = 31752
- 109 + 31643 = 31752
Showing the first eight; more decompositions exist.
