Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625572, here are decompositions:

13 + 8625559 = 8625572
19 + 8625553 = 8625572
31 + 8625541 = 8625572
79 + 8625493 = 8625572
223 + 8625349 = 8625572
229 + 8625343 = 8625572
271 + 8625301 = 8625572
283 + 8625289 = 8625572

Showing the first eight; more decompositions exist.
