Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619672, here are decompositions:

11 + 8619661 = 8619672
23 + 8619649 = 8619672
71 + 8619601 = 8619672
79 + 8619593 = 8619672
163 + 8619509 = 8619672
181 + 8619491 = 8619672
199 + 8619473 = 8619672
211 + 8619461 = 8619672

Showing the first eight; more decompositions exist.
