Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659786, here are decompositions:

17 + 8659769 = 8659786
197 + 8659589 = 8659786
227 + 8659559 = 8659786
563 + 8659223 = 8659786
719 + 8659067 = 8659786
743 + 8659043 = 8659786
797 + 8658989 = 8659786
809 + 8658977 = 8659786

Showing the first eight; more decompositions exist.
