Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975808, here are decompositions:
- 61 + 4294975747 = 4294975808
- 181 + 4294975627 = 4294975808
- 271 + 4294975537 = 4294975808
- 337 + 4294975471 = 4294975808
- 397 + 4294975411 = 4294975808
- 439 + 4294975369 = 4294975808
- 661 + 4294975147 = 4294975808
- 691 + 4294975117 = 4294975808
Showing the first eight; more decompositions exist.
