Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668208, here are decompositions:

7 + 8668201 = 8668208
67 + 8668141 = 8668208
97 + 8668111 = 8668208
127 + 8668081 = 8668208
151 + 8668057 = 8668208
229 + 8667979 = 8668208
277 + 8667931 = 8668208
337 + 8667871 = 8668208

Showing the first eight; more decompositions exist.
