Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967878, here are decompositions:
- 11 + 4294967867 = 4294967878
- 17 + 4294967861 = 4294967878
- 191 + 4294967687 = 4294967878
- 197 + 4294967681 = 4294967878
- 239 + 4294967639 = 4294967878
- 251 + 4294967627 = 4294967878
- 281 + 4294967597 = 4294967878
- 317 + 4294967561 = 4294967878
Showing the first eight; more decompositions exist.
