Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722810, here are decompositions:

11 + 8722799 = 8722810
53 + 8722757 = 8722810
71 + 8722739 = 8722810
137 + 8722673 = 8722810
149 + 8722661 = 8722810
167 + 8722643 = 8722810
179 + 8722631 = 8722810
197 + 8722613 = 8722810

Showing the first eight; more decompositions exist.
