Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668662, here are decompositions:

19 + 8668643 = 8668662
53 + 8668609 = 8668662
109 + 8668553 = 8668662
113 + 8668549 = 8668662
139 + 8668523 = 8668662
173 + 8668489 = 8668662
179 + 8668483 = 8668662
239 + 8668423 = 8668662

Showing the first eight; more decompositions exist.
