Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647668, here are decompositions:

11 + 8647657 = 8647668
79 + 8647589 = 8647668
89 + 8647579 = 8647668
101 + 8647567 = 8647668
131 + 8647537 = 8647668
137 + 8647531 = 8647668
157 + 8647511 = 8647668
167 + 8647501 = 8647668

Showing the first eight; more decompositions exist.
