Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609928, here are decompositions:

11 + 8609917 = 8609928
17 + 8609911 = 8609928
29 + 8609899 = 8609928
37 + 8609891 = 8609928
79 + 8609849 = 8609928
109 + 8609819 = 8609928
137 + 8609791 = 8609928
199 + 8609729 = 8609928

Showing the first eight; more decompositions exist.
