Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668068, here are decompositions:

5 + 8668063 = 8668068
7 + 8668061 = 8668068
11 + 8668057 = 8668068
37 + 8668031 = 8668068
67 + 8668001 = 8668068
89 + 8667979 = 8668068
107 + 8667961 = 8668068
137 + 8667931 = 8668068

Showing the first eight; more decompositions exist.
