Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600220, here are decompositions:

7 + 8600213 = 8600220
59 + 8600161 = 8600220
127 + 8600093 = 8600220
131 + 8600089 = 8600220
149 + 8600071 = 8600220
157 + 8600063 = 8600220
173 + 8600047 = 8600220
179 + 8600041 = 8600220

Showing the first eight; more decompositions exist.
