Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729918, here are decompositions:

31 + 8729887 = 8729918
37 + 8729881 = 8729918
79 + 8729839 = 8729918
97 + 8729821 = 8729918
151 + 8729767 = 8729918
229 + 8729689 = 8729918
271 + 8729647 = 8729918
277 + 8729641 = 8729918

Showing the first eight; more decompositions exist.
