Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729736, here are decompositions:

7 + 8729729 = 8729736
19 + 8729717 = 8729736
47 + 8729689 = 8729736
89 + 8729647 = 8729736
107 + 8729629 = 8729736
173 + 8729563 = 8729736
179 + 8729557 = 8729736
193 + 8729543 = 8729736

Showing the first eight; more decompositions exist.
