Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40680, here are decompositions:
- 41 + 40639 = 40680
- 43 + 40637 = 40680
- 53 + 40627 = 40680
- 71 + 40609 = 40680
- 83 + 40597 = 40680
- 89 + 40591 = 40680
- 97 + 40583 = 40680
- 103 + 40577 = 40680
Showing the first eight; more decompositions exist.
