Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967866, here are decompositions:
- 5 + 4294967861 = 4294967866
- 83 + 4294967783 = 4294967866
- 107 + 4294967759 = 4294967866
- 179 + 4294967687 = 4294967866
- 227 + 4294967639 = 4294967866
- 239 + 4294967627 = 4294967866
- 269 + 4294967597 = 4294967866
- 317 + 4294967549 = 4294967866
Showing the first eight; more decompositions exist.
