Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967644, here are decompositions:
- 5 + 4294967639 = 4294967644
- 17 + 4294967627 = 4294967644
- 47 + 4294967597 = 4294967644
- 83 + 4294967561 = 4294967644
- 101 + 4294967543 = 4294967644
- 131 + 4294967513 = 4294967644
- 167 + 4294967477 = 4294967644
- 257 + 4294967387 = 4294967644
Showing the first eight; more decompositions exist.
