Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617666, here are decompositions:

227 + 8617439 = 8617666
269 + 8617397 = 8617666
293 + 8617373 = 8617666
347 + 8617319 = 8617666
353 + 8617313 = 8617666
389 + 8617277 = 8617666
479 + 8617187 = 8617666
557 + 8617109 = 8617666

Showing the first eight; more decompositions exist.
