Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668118, here are decompositions:

7 + 8668111 = 8668118
37 + 8668081 = 8668118
61 + 8668057 = 8668118
139 + 8667979 = 8668118
157 + 8667961 = 8668118
211 + 8667907 = 8668118
271 + 8667847 = 8668118
397 + 8667721 = 8668118

Showing the first eight; more decompositions exist.
