Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974870, here are decompositions:
- 7 + 4294974863 = 4294974870
- 59 + 4294974811 = 4294974870
- 101 + 4294974769 = 4294974870
- 127 + 4294974743 = 4294974870
- 139 + 4294974731 = 4294974870
- 223 + 4294974647 = 4294974870
- 229 + 4294974641 = 4294974870
- 271 + 4294974599 = 4294974870
Showing the first eight; more decompositions exist.
