Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717578, here are decompositions:

47 + 8717531 = 8717578
461 + 8717117 = 8717578
557 + 8717021 = 8717578
659 + 8716919 = 8717578
761 + 8716817 = 8717578
809 + 8716769 = 8717578
887 + 8716691 = 8717578
1109 + 8716469 = 8717578

Showing the first eight; more decompositions exist.
