Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668008, here are decompositions:

7 + 8668001 = 8668008
29 + 8667979 = 8668008
47 + 8667961 = 8668008
59 + 8667949 = 8668008
79 + 8667929 = 8668008
101 + 8667907 = 8668008
109 + 8667899 = 8668008
137 + 8667871 = 8668008

Showing the first eight; more decompositions exist.
