Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617540, here are decompositions:

17 + 8617523 = 8617540
101 + 8617439 = 8617540
149 + 8617391 = 8617540
167 + 8617373 = 8617540
179 + 8617361 = 8617540
227 + 8617313 = 8617540
263 + 8617277 = 8617540
353 + 8617187 = 8617540

Showing the first eight; more decompositions exist.
