Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649572, here are decompositions:

103 + 8649469 = 8649572
109 + 8649463 = 8649572
163 + 8649409 = 8649572
181 + 8649391 = 8649572
223 + 8649349 = 8649572
229 + 8649343 = 8649572
241 + 8649331 = 8649572
331 + 8649241 = 8649572

Showing the first eight; more decompositions exist.
