Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647634, here are decompositions:

67 + 8647567 = 8647634
97 + 8647537 = 8647634
103 + 8647531 = 8647634
223 + 8647411 = 8647634
241 + 8647393 = 8647634
571 + 8647063 = 8647634
607 + 8647027 = 8647634
613 + 8647021 = 8647634

Showing the first eight; more decompositions exist.
