Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659638, here are decompositions:

7 + 8659631 = 8659638
11 + 8659627 = 8659638
37 + 8659601 = 8659638
79 + 8659559 = 8659638
101 + 8659537 = 8659638
107 + 8659531 = 8659638
137 + 8659501 = 8659638
167 + 8659471 = 8659638

Showing the first eight; more decompositions exist.
