Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615660, here are decompositions:

3 + 8615657 = 8615660
7 + 8615653 = 8615660
37 + 8615623 = 8615660
73 + 8615587 = 8615660
181 + 8615479 = 8615660
199 + 8615461 = 8615660
271 + 8615389 = 8615660
283 + 8615377 = 8615660

Showing the first eight; more decompositions exist.
