Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609628, here are decompositions:

7 + 8609621 = 8609628
11 + 8609617 = 8609628
17 + 8609611 = 8609628
19 + 8609609 = 8609628
31 + 8609597 = 8609628
37 + 8609591 = 8609628
47 + 8609581 = 8609628
59 + 8609569 = 8609628

Showing the first eight; more decompositions exist.
