Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717728, here are decompositions:

11 + 8717717 = 8717728
137 + 8717591 = 8717728
197 + 8717531 = 8717728
557 + 8717171 = 8717728
809 + 8716919 = 8717728
839 + 8716889 = 8717728
911 + 8716817 = 8717728
1019 + 8716709 = 8717728

Showing the first eight; more decompositions exist.
