Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971188, here are decompositions:

11 + 971177 = 971188
17 + 971171 = 971188
47 + 971141 = 971188
89 + 971099 = 971188
137 + 971051 = 971188
149 + 971039 = 971188
167 + 971021 = 971188
191 + 970997 = 971188

Showing the first eight; more decompositions exist.
