Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668016, here are decompositions:

37 + 8667979 = 8668016
43 + 8667973 = 8668016
67 + 8667949 = 8668016
103 + 8667913 = 8668016
109 + 8667907 = 8668016
223 + 8667793 = 8668016
283 + 8667733 = 8668016
457 + 8667559 = 8668016

Showing the first eight; more decompositions exist.
