Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668028, here are decompositions:

67 + 8667961 = 8668028
79 + 8667949 = 8668028
97 + 8667931 = 8668028
157 + 8667871 = 8668028
181 + 8667847 = 8668028
199 + 8667829 = 8668028
307 + 8667721 = 8668028
331 + 8667697 = 8668028

Showing the first eight; more decompositions exist.
