Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647680, here are decompositions:

23 + 8647657 = 8647680
101 + 8647579 = 8647680
113 + 8647567 = 8647680
149 + 8647531 = 8647680
179 + 8647501 = 8647680
211 + 8647469 = 8647680
233 + 8647447 = 8647680
263 + 8647417 = 8647680

Showing the first eight; more decompositions exist.
