Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645566, here are decompositions:

23 + 8645543 = 8645566
89 + 8645477 = 8645566
239 + 8645327 = 8645566
443 + 8645123 = 8645566
557 + 8645009 = 8645566
617 + 8644949 = 8645566
647 + 8644919 = 8645566
653 + 8644913 = 8645566

Showing the first eight; more decompositions exist.
