Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40698, here are decompositions:
- 5 + 40693 = 40698
- 59 + 40639 = 40698
- 61 + 40637 = 40698
- 71 + 40627 = 40698
- 89 + 40609 = 40698
- 101 + 40597 = 40698
- 107 + 40591 = 40698
- 139 + 40559 = 40698
Showing the first eight; more decompositions exist.
