Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975838, here are decompositions:
- 211 + 4294975627 = 4294975838
- 277 + 4294975561 = 4294975838
- 367 + 4294975471 = 4294975838
- 421 + 4294975417 = 4294975838
- 499 + 4294975339 = 4294975838
- 541 + 4294975297 = 4294975838
- 691 + 4294975147 = 4294975838
- 787 + 4294975051 = 4294975838
Showing the first eight; more decompositions exist.
