Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31954, here are decompositions:
- 47 + 31907 = 31954
- 71 + 31883 = 31954
- 107 + 31847 = 31954
- 137 + 31817 = 31954
- 227 + 31727 = 31954
- 233 + 31721 = 31954
- 311 + 31643 = 31954
- 347 + 31607 = 31954
Showing the first eight; more decompositions exist.
