Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675666, here are decompositions:

157 + 8675509 = 8675666
163 + 8675503 = 8675666
193 + 8675473 = 8675666
283 + 8675383 = 8675666
607 + 8675059 = 8675666
613 + 8675053 = 8675666
619 + 8675047 = 8675666
739 + 8674927 = 8675666

Showing the first eight; more decompositions exist.
