Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678, here are decompositions:
- 31 + 8647 = 8678
- 37 + 8641 = 8678
- 79 + 8599 = 8678
- 97 + 8581 = 8678
- 139 + 8539 = 8678
- 151 + 8527 = 8678
- 157 + 8521 = 8678
- 211 + 8467 = 8678
Showing the first eight; more decompositions exist.
