Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17690, here are decompositions:
- 7 + 17683 = 17690
- 31 + 17659 = 17690
- 67 + 17623 = 17690
- 109 + 17581 = 17690
- 139 + 17551 = 17690
- 151 + 17539 = 17690
- 181 + 17509 = 17690
- 193 + 17497 = 17690
Showing the first eight; more decompositions exist.
