Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722908, here are decompositions:

17 + 8722891 = 8722908
31 + 8722877 = 8722908
67 + 8722841 = 8722908
79 + 8722829 = 8722908
109 + 8722799 = 8722908
151 + 8722757 = 8722908
197 + 8722711 = 8722908
277 + 8722631 = 8722908

Showing the first eight; more decompositions exist.
