Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976644, here are decompositions:
- 5 + 4294976639 = 4294976644
- 17 + 4294976627 = 4294976644
- 107 + 4294976537 = 4294976644
- 191 + 4294976453 = 4294976644
- 197 + 4294976447 = 4294976644
- 227 + 4294976417 = 4294976644
- 263 + 4294976381 = 4294976644
- 383 + 4294976261 = 4294976644
Showing the first eight; more decompositions exist.
