Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632572, here are decompositions:

41 + 8632531 = 8632572
43 + 8632529 = 8632572
59 + 8632513 = 8632572
79 + 8632493 = 8632572
83 + 8632489 = 8632572
149 + 8632423 = 8632572
173 + 8632399 = 8632572
181 + 8632391 = 8632572

Showing the first eight; more decompositions exist.
