Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605224, here are decompositions:

7 + 8605217 = 8605224
13 + 8605211 = 8605224
37 + 8605187 = 8605224
53 + 8605171 = 8605224
71 + 8605153 = 8605224
163 + 8605061 = 8605224
167 + 8605057 = 8605224
223 + 8605001 = 8605224

Showing the first eight; more decompositions exist.
