Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605000, here are decompositions:

17 + 8604983 = 8605000
23 + 8604977 = 8605000
137 + 8604863 = 8605000
191 + 8604809 = 8605000
233 + 8604767 = 8605000
251 + 8604749 = 8605000
293 + 8604707 = 8605000
311 + 8604689 = 8605000

Showing the first eight; more decompositions exist.
