Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975638, here are decompositions:
- 11 + 4294975627 = 4294975638
- 101 + 4294975537 = 4294975638
- 139 + 4294975499 = 4294975638
- 167 + 4294975471 = 4294975638
- 227 + 4294975411 = 4294975638
- 241 + 4294975397 = 4294975638
- 269 + 4294975369 = 4294975638
- 409 + 4294975229 = 4294975638
Showing the first eight; more decompositions exist.
