Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975778, here are decompositions:
- 31 + 4294975747 = 4294975778
- 61 + 4294975717 = 4294975778
- 151 + 4294975627 = 4294975778
- 241 + 4294975537 = 4294975778
- 307 + 4294975471 = 4294975778
- 367 + 4294975411 = 4294975778
- 409 + 4294975369 = 4294975778
- 439 + 4294975339 = 4294975778
Showing the first eight; more decompositions exist.
