Goldbach decomposition

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.
