Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663666, here are decompositions:

13 + 8663653 = 8663666
73 + 8663593 = 8663666
157 + 8663509 = 8663666
163 + 8663503 = 8663666
199 + 8663467 = 8663666
229 + 8663437 = 8663666
457 + 8663209 = 8663666
547 + 8663119 = 8663666

Showing the first eight; more decompositions exist.
