Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606178, here are decompositions:

5 + 8606173 = 8606178
41 + 8606137 = 8606178
101 + 8606077 = 8606178
127 + 8606051 = 8606178
131 + 8606047 = 8606178
137 + 8606041 = 8606178
179 + 8605999 = 8606178
181 + 8605997 = 8606178

Showing the first eight; more decompositions exist.
