Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51664, here are decompositions:
- 5 + 51659 = 51664
- 17 + 51647 = 51664
- 71 + 51593 = 51664
- 83 + 51581 = 51664
- 101 + 51563 = 51664
- 113 + 51551 = 51664
- 191 + 51473 = 51664
- 227 + 51437 = 51664
Showing the first eight; more decompositions exist.
