Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530368, here are decompositions:
- 19 + 31530349 = 31530368
- 157 + 31530211 = 31530368
- 271 + 31530097 = 31530368
- 307 + 31530061 = 31530368
- 367 + 31530001 = 31530368
- 487 + 31529881 = 31530368
- 619 + 31529749 = 31530368
- 691 + 31529677 = 31530368
Showing the first eight; more decompositions exist.
