Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659566, here are decompositions:

7 + 8659559 = 8659566
23 + 8659543 = 8659566
29 + 8659537 = 8659566
53 + 8659513 = 8659566
103 + 8659463 = 8659566
109 + 8659457 = 8659566
173 + 8659393 = 8659566
257 + 8659309 = 8659566

Showing the first eight; more decompositions exist.
