Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729676, here are decompositions:

17 + 8729659 = 8729676
29 + 8729647 = 8729676
47 + 8729629 = 8729676
73 + 8729603 = 8729676
83 + 8729593 = 8729676
113 + 8729563 = 8729676
349 + 8729327 = 8729676
353 + 8729323 = 8729676

Showing the first eight; more decompositions exist.
