Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601668, here are decompositions:

37 + 8601631 = 8601668
157 + 8601511 = 8601668
211 + 8601457 = 8601668
277 + 8601391 = 8601668
307 + 8601361 = 8601668
337 + 8601331 = 8601668
379 + 8601289 = 8601668
499 + 8601169 = 8601668

Showing the first eight; more decompositions exist.
