Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729682, here are decompositions:

23 + 8729659 = 8729682
41 + 8729641 = 8729682
53 + 8729629 = 8729682
61 + 8729621 = 8729682
79 + 8729603 = 8729682
89 + 8729593 = 8729682
139 + 8729543 = 8729682
191 + 8729491 = 8729682

Showing the first eight; more decompositions exist.
