Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617572, here are decompositions:

11 + 8617561 = 8617572
23 + 8617549 = 8617572
53 + 8617519 = 8617572
59 + 8617513 = 8617572
181 + 8617391 = 8617572
191 + 8617381 = 8617572
199 + 8617373 = 8617572
211 + 8617361 = 8617572

Showing the first eight; more decompositions exist.
