Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729672, here are decompositions:

13 + 8729659 = 8729672
31 + 8729641 = 8729672
43 + 8729629 = 8729672
79 + 8729593 = 8729672
109 + 8729563 = 8729672
181 + 8729491 = 8729672
271 + 8729401 = 8729672
283 + 8729389 = 8729672

Showing the first eight; more decompositions exist.
