Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659672, here are decompositions:

3 + 8659669 = 8659672
5 + 8659667 = 8659672
29 + 8659643 = 8659672
41 + 8659631 = 8659672
71 + 8659601 = 8659672
83 + 8659589 = 8659672
113 + 8659559 = 8659672
383 + 8659289 = 8659672

Showing the first eight; more decompositions exist.
