Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530386, here are decompositions:
- 3 + 31530383 = 31530386
- 37 + 31530349 = 31530386
- 409 + 31529977 = 31530386
- 463 + 31529923 = 31530386
- 487 + 31529899 = 31530386
- 709 + 31529677 = 31530386
- 757 + 31529629 = 31530386
- 829 + 31529557 = 31530386
Showing the first eight; more decompositions exist.
