Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725572, here are decompositions:

5 + 8725567 = 8725572
41 + 8725531 = 8725572
61 + 8725511 = 8725572
73 + 8725499 = 8725572
83 + 8725489 = 8725572
109 + 8725463 = 8725572
113 + 8725459 = 8725572
151 + 8725421 = 8725572

Showing the first eight; more decompositions exist.
