Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729718, here are decompositions:

7 + 8729711 = 8729718
29 + 8729689 = 8729718
37 + 8729681 = 8729718
59 + 8729659 = 8729718
71 + 8729647 = 8729718
89 + 8729629 = 8729718
97 + 8729621 = 8729718
227 + 8729491 = 8729718

Showing the first eight; more decompositions exist.
