Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626572, here are decompositions:

23 + 8626549 = 8626572
43 + 8626529 = 8626572
79 + 8626493 = 8626572
103 + 8626469 = 8626572
113 + 8626459 = 8626572
151 + 8626421 = 8626572
181 + 8626391 = 8626572
223 + 8626349 = 8626572

Showing the first eight; more decompositions exist.
