Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668238, here are decompositions:

31 + 8668207 = 8668238
37 + 8668201 = 8668238
97 + 8668141 = 8668238
127 + 8668111 = 8668238
157 + 8668081 = 8668238
181 + 8668057 = 8668238
277 + 8667961 = 8668238
307 + 8667931 = 8668238

Showing the first eight; more decompositions exist.
