Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729894, here are decompositions:

7 + 8729887 = 8729894
13 + 8729881 = 8729894
73 + 8729821 = 8729894
127 + 8729767 = 8729894
331 + 8729563 = 8729894
337 + 8729557 = 8729894
571 + 8729323 = 8729894
577 + 8729317 = 8729894

Showing the first eight; more decompositions exist.
