Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31676, here are decompositions:
- 13 + 31663 = 31676
- 19 + 31657 = 31676
- 103 + 31573 = 31676
- 109 + 31567 = 31676
- 163 + 31513 = 31676
- 199 + 31477 = 31676
- 283 + 31393 = 31676
- 349 + 31327 = 31676
Showing the first eight; more decompositions exist.
