Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971686, here are decompositions:
- 13 + 4294971673 = 4294971686
- 43 + 4294971643 = 4294971686
- 79 + 4294971607 = 4294971686
- 307 + 4294971379 = 4294971686
- 337 + 4294971349 = 4294971686
- 487 + 4294971199 = 4294971686
- 613 + 4294971073 = 4294971686
- 823 + 4294970863 = 4294971686
Showing the first eight; more decompositions exist.
