Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623188, here are decompositions:

47 + 8623141 = 8623188
107 + 8623081 = 8623188
127 + 8623061 = 8623188
137 + 8623051 = 8623188
149 + 8623039 = 8623188
151 + 8623037 = 8623188
157 + 8623031 = 8623188
229 + 8622959 = 8623188

Showing the first eight; more decompositions exist.
