Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668654, here are decompositions:

11 + 8668643 = 8668654
17 + 8668637 = 8668654
41 + 8668613 = 8668654
83 + 8668571 = 8668654
101 + 8668553 = 8668654
107 + 8668547 = 8668654
131 + 8668523 = 8668654
233 + 8668421 = 8668654

Showing the first eight; more decompositions exist.
