Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622864, here are decompositions:

7 + 8622857 = 8622864
11 + 8622853 = 8622864
17 + 8622847 = 8622864
23 + 8622841 = 8622864
53 + 8622811 = 8622864
71 + 8622793 = 8622864
83 + 8622781 = 8622864
97 + 8622767 = 8622864

Showing the first eight; more decompositions exist.
