Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668138, here are decompositions:

5 + 8668133 = 8668138
71 + 8668067 = 8668138
107 + 8668031 = 8668138
137 + 8668001 = 8668138
239 + 8667899 = 8668138
317 + 8667821 = 8668138
431 + 8667707 = 8668138
449 + 8667689 = 8668138

Showing the first eight; more decompositions exist.
