Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722930, here are decompositions:

17 + 8722913 = 8722930
53 + 8722877 = 8722930
71 + 8722859 = 8722930
89 + 8722841 = 8722930
101 + 8722829 = 8722930
131 + 8722799 = 8722930
173 + 8722757 = 8722930
191 + 8722739 = 8722930

Showing the first eight; more decompositions exist.
