Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967640, here are decompositions:
- 13 + 4294967627 = 4294967640
- 43 + 4294967597 = 4294967640
- 71 + 4294967569 = 4294967640
- 79 + 4294967561 = 4294967640
- 97 + 4294967543 = 4294967640
- 101 + 4294967539 = 4294967640
- 127 + 4294967513 = 4294967640
- 163 + 4294967477 = 4294967640
Showing the first eight; more decompositions exist.
