Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639916, here are decompositions:

7 + 8639909 = 8639916
13 + 8639903 = 8639916
17 + 8639899 = 8639916
53 + 8639863 = 8639916
67 + 8639849 = 8639916
79 + 8639837 = 8639916
97 + 8639819 = 8639916
107 + 8639809 = 8639916

Showing the first eight; more decompositions exist.
