Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729656, here are decompositions:

53 + 8729603 = 8729656
113 + 8729543 = 8729656
227 + 8729429 = 8729656
347 + 8729309 = 8729656
449 + 8729207 = 8729656
557 + 8729099 = 8729656
563 + 8729093 = 8729656
599 + 8729057 = 8729656

Showing the first eight; more decompositions exist.
