Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975818, here are decompositions:
- 37 + 4294975781 = 4294975818
- 61 + 4294975757 = 4294975818
- 71 + 4294975747 = 4294975818
- 79 + 4294975739 = 4294975818
- 101 + 4294975717 = 4294975818
- 191 + 4294975627 = 4294975818
- 229 + 4294975589 = 4294975818
- 257 + 4294975561 = 4294975818
Showing the first eight; more decompositions exist.
