Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659642, here are decompositions:

11 + 8659631 = 8659642
41 + 8659601 = 8659642
53 + 8659589 = 8659642
83 + 8659559 = 8659642
179 + 8659463 = 8659642
353 + 8659289 = 8659642
419 + 8659223 = 8659642
461 + 8659181 = 8659642

Showing the first eight; more decompositions exist.
