Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967728, here are decompositions:
- 5 + 4294967723 = 4294967728
- 41 + 4294967687 = 4294967728
- 47 + 4294967681 = 4294967728
- 89 + 4294967639 = 4294967728
- 101 + 4294967627 = 4294967728
- 131 + 4294967597 = 4294967728
- 167 + 4294967561 = 4294967728
- 179 + 4294967549 = 4294967728
Showing the first eight; more decompositions exist.
