Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976638, here are decompositions:
- 11 + 4294976627 = 4294976638
- 59 + 4294976579 = 4294976638
- 89 + 4294976549 = 4294976638
- 101 + 4294976537 = 4294976638
- 137 + 4294976501 = 4294976638
- 191 + 4294976447 = 4294976638
- 257 + 4294976381 = 4294976638
- 317 + 4294976321 = 4294976638
Showing the first eight; more decompositions exist.
