Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623572, here are decompositions:

43 + 8623529 = 8623572
53 + 8623519 = 8623572
149 + 8623423 = 8623572
163 + 8623409 = 8623572
179 + 8623393 = 8623572
233 + 8623339 = 8623572
281 + 8623291 = 8623572
311 + 8623261 = 8623572

Showing the first eight; more decompositions exist.
