Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668178, here are decompositions:

37 + 8668141 = 8668178
67 + 8668111 = 8668178
97 + 8668081 = 8668178
199 + 8667979 = 8668178
229 + 8667949 = 8668178
271 + 8667907 = 8668178
307 + 8667871 = 8668178
331 + 8667847 = 8668178

Showing the first eight; more decompositions exist.
