Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606620, here are decompositions:

17 + 8606603 = 8606620
83 + 8606537 = 8606620
167 + 8606453 = 8606620
173 + 8606447 = 8606620
179 + 8606441 = 8606620
233 + 8606387 = 8606620
257 + 8606363 = 8606620
293 + 8606327 = 8606620

Showing the first eight; more decompositions exist.
