Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31960, here are decompositions:
- 3 + 31957 = 31960
- 53 + 31907 = 31960
- 101 + 31859 = 31960
- 113 + 31847 = 31960
- 167 + 31793 = 31960
- 191 + 31769 = 31960
- 233 + 31727 = 31960
- 239 + 31721 = 31960
Showing the first eight; more decompositions exist.
