Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639922, here are decompositions:

13 + 8639909 = 8639922
19 + 8639903 = 8639922
23 + 8639899 = 8639922
59 + 8639863 = 8639922
73 + 8639849 = 8639922
103 + 8639819 = 8639922
113 + 8639809 = 8639922
149 + 8639773 = 8639922

Showing the first eight; more decompositions exist.
