Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86688, here are decompositions:
- 11 + 86677 = 86688
- 59 + 86629 = 86688
- 61 + 86627 = 86688
- 89 + 86599 = 86688
- 101 + 86587 = 86688
- 109 + 86579 = 86688
- 127 + 86561 = 86688
- 149 + 86539 = 86688
Showing the first eight; more decompositions exist.
