Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975728, here are decompositions:
- 11 + 4294975717 = 4294975728
- 31 + 4294975697 = 4294975728
- 79 + 4294975649 = 4294975728
- 101 + 4294975627 = 4294975728
- 139 + 4294975589 = 4294975728
- 167 + 4294975561 = 4294975728
- 181 + 4294975547 = 4294975728
- 191 + 4294975537 = 4294975728
Showing the first eight; more decompositions exist.
