Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717818, here are decompositions:

71 + 8717747 = 8717818
101 + 8717717 = 8717818
227 + 8717591 = 8717818
617 + 8717201 = 8717818
647 + 8717171 = 8717818
701 + 8717117 = 8717818
797 + 8717021 = 8717818
821 + 8716997 = 8717818

Showing the first eight; more decompositions exist.
