Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618572, here are decompositions:

5 + 8618567 = 8618572
71 + 8618501 = 8618572
89 + 8618483 = 8618572
233 + 8618339 = 8618572
359 + 8618213 = 8618572
509 + 8618063 = 8618572
701 + 8617871 = 8618572
773 + 8617799 = 8618572

Showing the first eight; more decompositions exist.
