Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605580, here are decompositions:

3 + 8605577 = 8605580
13 + 8605567 = 8605580
19 + 8605561 = 8605580
37 + 8605543 = 8605580
79 + 8605501 = 8605580
211 + 8605369 = 8605580
283 + 8605297 = 8605580
307 + 8605273 = 8605580

Showing the first eight; more decompositions exist.
