Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668166, here are decompositions:

103 + 8668063 = 8668166
109 + 8668057 = 8668166
193 + 8667973 = 8668166
337 + 8667829 = 8668166
373 + 8667793 = 8668166
433 + 8667733 = 8668166
439 + 8667727 = 8668166
607 + 8667559 = 8668166

Showing the first eight; more decompositions exist.
