Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975642, here are decompositions:
- 53 + 4294975589 = 4294975642
- 179 + 4294975463 = 4294975642
- 431 + 4294975211 = 4294975642
- 479 + 4294975163 = 4294975642
- 563 + 4294975079 = 4294975642
- 599 + 4294975043 = 4294975642
- 719 + 4294974923 = 4294975642
- 761 + 4294974881 = 4294975642
Showing the first eight; more decompositions exist.
