Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971656, here are decompositions:
- 13 + 4294971643 = 4294971656
- 277 + 4294971379 = 4294971656
- 307 + 4294971349 = 4294971656
- 457 + 4294971199 = 4294971656
- 487 + 4294971169 = 4294971656
- 733 + 4294970923 = 4294971656
- 907 + 4294970749 = 4294971656
- 1087 + 4294970569 = 4294971656
Showing the first eight; more decompositions exist.
