Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729604, here are decompositions:

11 + 8729593 = 8729604
41 + 8729563 = 8729604
47 + 8729557 = 8729604
61 + 8729543 = 8729604
113 + 8729491 = 8729604
137 + 8729467 = 8729604
193 + 8729411 = 8729604
271 + 8729333 = 8729604

Showing the first eight; more decompositions exist.
