Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609886, here are decompositions:

7 + 8609879 = 8609886
37 + 8609849 = 8609886
53 + 8609833 = 8609886
67 + 8609819 = 8609886
73 + 8609813 = 8609886
113 + 8609773 = 8609886
157 + 8609729 = 8609886
167 + 8609719 = 8609886

Showing the first eight; more decompositions exist.
