Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668142, here are decompositions:

31 + 8668111 = 8668142
61 + 8668081 = 8668142
79 + 8668063 = 8668142
163 + 8667979 = 8668142
181 + 8667961 = 8668142
193 + 8667949 = 8668142
211 + 8667931 = 8668142
229 + 8667913 = 8668142

Showing the first eight; more decompositions exist.
