Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729666, here are decompositions:

7 + 8729659 = 8729666
19 + 8729647 = 8729666
37 + 8729629 = 8729666
73 + 8729593 = 8729666
103 + 8729563 = 8729666
109 + 8729557 = 8729666
199 + 8729467 = 8729666
277 + 8729389 = 8729666

Showing the first eight; more decompositions exist.
