Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729652, here are decompositions:

5 + 8729647 = 8729652
11 + 8729641 = 8729652
23 + 8729629 = 8729652
31 + 8729621 = 8729652
59 + 8729593 = 8729652
89 + 8729563 = 8729652
109 + 8729543 = 8729652
223 + 8729429 = 8729652

Showing the first eight; more decompositions exist.
