Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625672, here are decompositions:

23 + 8625649 = 8625672
31 + 8625641 = 8625672
73 + 8625599 = 8625672
113 + 8625559 = 8625672
131 + 8625541 = 8625672
151 + 8625521 = 8625672
163 + 8625509 = 8625672
179 + 8625493 = 8625672

Showing the first eight; more decompositions exist.
