Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612660, here are decompositions:

3 + 8612657 = 8612660
19 + 8612641 = 8612660
31 + 8612629 = 8612660
79 + 8612581 = 8612660
157 + 8612503 = 8612660
163 + 8612497 = 8612660
181 + 8612479 = 8612660
223 + 8612437 = 8612660

Showing the first eight; more decompositions exist.
