Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668658, here are decompositions:

109 + 8668549 = 8668658
139 + 8668519 = 8668658
157 + 8668501 = 8668658
199 + 8668459 = 8668658
277 + 8668381 = 8668658
379 + 8668279 = 8668658
457 + 8668201 = 8668658
547 + 8668111 = 8668658

Showing the first eight; more decompositions exist.
