Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758660, here are decompositions:

23 + 8758637 = 8758660
83 + 8758577 = 8758660
149 + 8758511 = 8758660
179 + 8758481 = 8758660
227 + 8758433 = 8758660
233 + 8758427 = 8758660
269 + 8758391 = 8758660
347 + 8758313 = 8758660

Showing the first eight; more decompositions exist.
