Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663660, here are decompositions:

7 + 8663653 = 8663660
67 + 8663593 = 8663660
139 + 8663521 = 8663660
151 + 8663509 = 8663660
157 + 8663503 = 8663660
163 + 8663497 = 8663660
193 + 8663467 = 8663660
199 + 8663461 = 8663660

Showing the first eight; more decompositions exist.
