Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660450, here are decompositions:

13 + 8660437 = 8660450
31 + 8660419 = 8660450
37 + 8660413 = 8660450
67 + 8660383 = 8660450
163 + 8660287 = 8660450
181 + 8660269 = 8660450
223 + 8660227 = 8660450
229 + 8660221 = 8660450

Showing the first eight; more decompositions exist.
