Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613572, here are decompositions:

13 + 8613559 = 8613572
43 + 8613529 = 8613572
109 + 8613463 = 8613572
151 + 8613421 = 8613572
181 + 8613391 = 8613572
193 + 8613379 = 8613572
223 + 8613349 = 8613572
571 + 8613001 = 8613572

Showing the first eight; more decompositions exist.
