Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967666, here are decompositions:
- 13 + 4294967653 = 4294967666
- 97 + 4294967569 = 4294967666
- 103 + 4294967563 = 4294967666
- 127 + 4294967539 = 4294967666
- 277 + 4294967389 = 4294967666
- 523 + 4294967143 = 4294967666
- 739 + 4294966927 = 4294967666
- 757 + 4294966909 = 4294967666
Showing the first eight; more decompositions exist.
