Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643766, here are decompositions:

17 + 8643749 = 8643766
59 + 8643707 = 8643766
179 + 8643587 = 8643766
227 + 8643539 = 8643766
239 + 8643527 = 8643766
449 + 8643317 = 8643766
479 + 8643287 = 8643766
557 + 8643209 = 8643766

Showing the first eight; more decompositions exist.
