Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975578, here are decompositions:
- 17 + 4294975561 = 4294975578
- 31 + 4294975547 = 4294975578
- 41 + 4294975537 = 4294975578
- 79 + 4294975499 = 4294975578
- 107 + 4294975471 = 4294975578
- 167 + 4294975411 = 4294975578
- 181 + 4294975397 = 4294975578
- 239 + 4294975339 = 4294975578
Showing the first eight; more decompositions exist.
