Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605008, here are decompositions:

7 + 8605001 = 8605008
17 + 8604991 = 8605008
31 + 8604977 = 8605008
47 + 8604961 = 8605008
197 + 8604811 = 8605008
199 + 8604809 = 8605008
211 + 8604797 = 8605008
227 + 8604781 = 8605008

Showing the first eight; more decompositions exist.
