Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40658, here are decompositions:
- 19 + 40639 = 40658
- 31 + 40627 = 40658
- 61 + 40597 = 40658
- 67 + 40591 = 40658
- 127 + 40531 = 40658
- 139 + 40519 = 40658
- 151 + 40507 = 40658
- 199 + 40459 = 40658
Showing the first eight; more decompositions exist.
