Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40668, here are decompositions:
- 29 + 40639 = 40668
- 31 + 40637 = 40668
- 41 + 40627 = 40668
- 59 + 40609 = 40668
- 71 + 40597 = 40668
- 109 + 40559 = 40668
- 137 + 40531 = 40668
- 139 + 40529 = 40668
Showing the first eight; more decompositions exist.
