Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668664, here are decompositions:

163 + 8668501 = 8668664
181 + 8668483 = 8668664
241 + 8668423 = 8668664
283 + 8668381 = 8668664
307 + 8668357 = 8668664
397 + 8668267 = 8668664
457 + 8668207 = 8668664
463 + 8668201 = 8668664

Showing the first eight; more decompositions exist.
