Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17658, here are decompositions:
- 31 + 17627 = 17658
- 59 + 17599 = 17658
- 61 + 17597 = 17658
- 79 + 17579 = 17658
- 89 + 17569 = 17658
- 107 + 17551 = 17658
- 139 + 17519 = 17658
- 149 + 17509 = 17658
Showing the first eight; more decompositions exist.
