Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605164, here are decompositions:

5 + 8605159 = 8605164
11 + 8605153 = 8605164
17 + 8605147 = 8605164
103 + 8605061 = 8605164
107 + 8605057 = 8605164
163 + 8605001 = 8605164
173 + 8604991 = 8605164
181 + 8604983 = 8605164

Showing the first eight; more decompositions exist.
