Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622870, here are decompositions:

13 + 8622857 = 8622870
17 + 8622853 = 8622870
23 + 8622847 = 8622870
29 + 8622841 = 8622870
59 + 8622811 = 8622870
89 + 8622781 = 8622870
103 + 8622767 = 8622870
107 + 8622763 = 8622870

Showing the first eight; more decompositions exist.
