Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647662, here are decompositions:

5 + 8647657 = 8647662
73 + 8647589 = 8647662
83 + 8647579 = 8647662
131 + 8647531 = 8647662
151 + 8647511 = 8647662
193 + 8647469 = 8647662
251 + 8647411 = 8647662
269 + 8647393 = 8647662

Showing the first eight; more decompositions exist.
