Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975988, here are decompositions:
- 97 + 4294975891 = 4294975988
- 139 + 4294975849 = 4294975988
- 241 + 4294975747 = 4294975988
- 271 + 4294975717 = 4294975988
- 571 + 4294975417 = 4294975988
- 577 + 4294975411 = 4294975988
- 619 + 4294975369 = 4294975988
- 691 + 4294975297 = 4294975988
Showing the first eight; more decompositions exist.
