Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66516, here are decompositions:
- 7 + 66509 = 66516
- 17 + 66499 = 66516
- 53 + 66463 = 66516
- 59 + 66457 = 66516
- 67 + 66449 = 66516
- 103 + 66413 = 66516
- 113 + 66403 = 66516
- 139 + 66377 = 66516
Showing the first eight; more decompositions exist.
