Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65688, here are decompositions:
- 11 + 65677 = 65688
- 31 + 65657 = 65688
- 37 + 65651 = 65688
- 41 + 65647 = 65688
- 59 + 65629 = 65688
- 71 + 65617 = 65688
- 79 + 65609 = 65688
- 89 + 65599 = 65688
Showing the first eight; more decompositions exist.
