Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729994, here are decompositions:

11 + 8729983 = 8729994
17 + 8729977 = 8729994
71 + 8729923 = 8729994
107 + 8729887 = 8729994
113 + 8729881 = 8729994
127 + 8729867 = 8729994
157 + 8729837 = 8729994
173 + 8729821 = 8729994

Showing the first eight; more decompositions exist.
