Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729808, here are decompositions:

7 + 8729801 = 8729808
41 + 8729767 = 8729808
79 + 8729729 = 8729808
97 + 8729711 = 8729808
127 + 8729681 = 8729808
149 + 8729659 = 8729808
167 + 8729641 = 8729808
179 + 8729629 = 8729808

Showing the first eight; more decompositions exist.
