Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729688, here are decompositions:

7 + 8729681 = 8729688
29 + 8729659 = 8729688
41 + 8729647 = 8729688
47 + 8729641 = 8729688
59 + 8729629 = 8729688
67 + 8729621 = 8729688
131 + 8729557 = 8729688
197 + 8729491 = 8729688

Showing the first eight; more decompositions exist.
