Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659666, here are decompositions:

3 + 8659663 = 8659666
23 + 8659643 = 8659666
107 + 8659559 = 8659666
443 + 8659223 = 8659666
569 + 8659097 = 8659666
599 + 8659067 = 8659666
647 + 8659019 = 8659666
677 + 8658989 = 8659666

Showing the first eight; more decompositions exist.
