Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17678, here are decompositions:
- 19 + 17659 = 17678
- 79 + 17599 = 17678
- 97 + 17581 = 17678
- 109 + 17569 = 17678
- 127 + 17551 = 17678
- 139 + 17539 = 17678
- 181 + 17497 = 17678
- 211 + 17467 = 17678
Showing the first eight; more decompositions exist.
