Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729966, here are decompositions:

43 + 8729923 = 8729966
79 + 8729887 = 8729966
97 + 8729869 = 8729966
127 + 8729839 = 8729966
199 + 8729767 = 8729966
277 + 8729689 = 8729966
307 + 8729659 = 8729966
337 + 8729629 = 8729966

Showing the first eight; more decompositions exist.
