Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659572, here are decompositions:

13 + 8659559 = 8659572
29 + 8659543 = 8659572
41 + 8659531 = 8659572
59 + 8659513 = 8659572
71 + 8659501 = 8659572
101 + 8659471 = 8659572
109 + 8659463 = 8659572
149 + 8659423 = 8659572

Showing the first eight; more decompositions exist.
