Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729984, here are decompositions:

7 + 8729977 = 8729984
61 + 8729923 = 8729984
97 + 8729887 = 8729984
103 + 8729881 = 8729984
163 + 8729821 = 8729984
337 + 8729647 = 8729984
421 + 8729563 = 8729984
661 + 8729323 = 8729984

Showing the first eight; more decompositions exist.
