Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722888, here are decompositions:

11 + 8722877 = 8722888
29 + 8722859 = 8722888
47 + 8722841 = 8722888
59 + 8722829 = 8722888
89 + 8722799 = 8722888
131 + 8722757 = 8722888
149 + 8722739 = 8722888
227 + 8722661 = 8722888

Showing the first eight; more decompositions exist.
