Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668366, here are decompositions:

17 + 8668349 = 8668366
173 + 8668193 = 8668366
233 + 8668133 = 8668366
293 + 8668073 = 8668366
467 + 8667899 = 8668366
503 + 8667863 = 8668366
557 + 8667809 = 8668366
569 + 8667797 = 8668366

Showing the first eight; more decompositions exist.
