Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668130, here are decompositions:

19 + 8668111 = 8668130
67 + 8668063 = 8668130
73 + 8668057 = 8668130
151 + 8667979 = 8668130
157 + 8667973 = 8668130
181 + 8667949 = 8668130
199 + 8667931 = 8668130
223 + 8667907 = 8668130

Showing the first eight; more decompositions exist.
