Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971812, here are decompositions:
- 31 + 4294971781 = 4294971812
- 139 + 4294971673 = 4294971812
- 421 + 4294971391 = 4294971812
- 433 + 4294971379 = 4294971812
- 463 + 4294971349 = 4294971812
- 613 + 4294971199 = 4294971812
- 643 + 4294971169 = 4294971812
- 661 + 4294971151 = 4294971812
Showing the first eight; more decompositions exist.
