Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647572, here are decompositions:

5 + 8647567 = 8647572
41 + 8647531 = 8647572
61 + 8647511 = 8647572
71 + 8647501 = 8647572
103 + 8647469 = 8647572
113 + 8647459 = 8647572
163 + 8647409 = 8647572
179 + 8647393 = 8647572

Showing the first eight; more decompositions exist.
