Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31330, here are decompositions:
- 3 + 31327 = 31330
- 11 + 31319 = 31330
- 23 + 31307 = 31330
- 53 + 31277 = 31330
- 59 + 31271 = 31330
- 71 + 31259 = 31330
- 83 + 31247 = 31330
- 107 + 31223 = 31330
Showing the first eight; more decompositions exist.
