Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645326, here are decompositions:

59 + 8645267 = 8645326
83 + 8645243 = 8645326
89 + 8645237 = 8645326
317 + 8645009 = 8645326
647 + 8644679 = 8645326
719 + 8644607 = 8645326
773 + 8644553 = 8645326
797 + 8644529 = 8645326

Showing the first eight; more decompositions exist.
