Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601628, here are decompositions:

41 + 8601587 = 8601628
47 + 8601581 = 8601628
59 + 8601569 = 8601628
71 + 8601557 = 8601628
137 + 8601491 = 8601628
179 + 8601449 = 8601628
227 + 8601401 = 8601628
239 + 8601389 = 8601628

Showing the first eight; more decompositions exist.
