Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294969886, here are decompositions:
- 73 + 4294969813 = 4294969886
- 79 + 4294969807 = 4294969886
- 127 + 4294969759 = 4294969886
- 139 + 4294969747 = 4294969886
- 157 + 4294969729 = 4294969886
- 223 + 4294969663 = 4294969886
- 397 + 4294969489 = 4294969886
- 457 + 4294969429 = 4294969886
Showing the first eight; more decompositions exist.
