Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967638, here are decompositions:
- 11 + 4294967627 = 4294967638
- 41 + 4294967597 = 4294967638
- 89 + 4294967549 = 4294967638
- 179 + 4294967459 = 4294967638
- 251 + 4294967387 = 4294967638
- 281 + 4294967357 = 4294967638
- 347 + 4294967291 = 4294967638
- 359 + 4294967279 = 4294967638
Showing the first eight; more decompositions exist.
