Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668406, here are decompositions:

3 + 8668403 = 8668406
37 + 8668369 = 8668406
127 + 8668279 = 8668406
139 + 8668267 = 8668406
199 + 8668207 = 8668406
349 + 8668057 = 8668406
433 + 8667973 = 8668406
457 + 8667949 = 8668406

Showing the first eight; more decompositions exist.
