Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40656, here are decompositions:
- 17 + 40639 = 40656
- 19 + 40637 = 40656
- 29 + 40627 = 40656
- 47 + 40609 = 40656
- 59 + 40597 = 40656
- 73 + 40583 = 40656
- 79 + 40577 = 40656
- 97 + 40559 = 40656
Showing the first eight; more decompositions exist.
