Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659744, here are decompositions:

3 + 8659741 = 8659744
53 + 8659691 = 8659744
101 + 8659643 = 8659744
113 + 8659631 = 8659744
281 + 8659463 = 8659744
521 + 8659223 = 8659744
563 + 8659181 = 8659744
647 + 8659097 = 8659744

Showing the first eight; more decompositions exist.
