Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680660, here are decompositions:

29 + 8680631 = 8680660
41 + 8680619 = 8680660
47 + 8680613 = 8680660
59 + 8680601 = 8680660
101 + 8680559 = 8680660
179 + 8680481 = 8680660
251 + 8680409 = 8680660
269 + 8680391 = 8680660

Showing the first eight; more decompositions exist.
