Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628572, here are decompositions:

19 + 8628553 = 8628572
79 + 8628493 = 8628572
109 + 8628463 = 8628572
151 + 8628421 = 8628572
223 + 8628349 = 8628572
523 + 8628049 = 8628572
541 + 8628031 = 8628572
619 + 8627953 = 8628572

Showing the first eight; more decompositions exist.
