Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648656, here are decompositions:

113 + 8648543 = 8648656
197 + 8648459 = 8648656
389 + 8648267 = 8648656
557 + 8648099 = 8648656
563 + 8648093 = 8648656
659 + 8647997 = 8648656
677 + 8647979 = 8648656
719 + 8647937 = 8648656

Showing the first eight; more decompositions exist.
