Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668668, here are decompositions:

31 + 8668637 = 8668668
59 + 8668609 = 8668668
97 + 8668571 = 8668668
149 + 8668519 = 8668668
167 + 8668501 = 8668668
179 + 8668489 = 8668668
311 + 8668357 = 8668668
367 + 8668301 = 8668668

Showing the first eight; more decompositions exist.
