Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684660, here are decompositions:

3 + 8684657 = 8684660
31 + 8684629 = 8684660
73 + 8684587 = 8684660
139 + 8684521 = 8684660
157 + 8684503 = 8684660
181 + 8684479 = 8684660
199 + 8684461 = 8684660
223 + 8684437 = 8684660

Showing the first eight; more decompositions exist.
