Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971158, here are decompositions:

5 + 971153 = 971158
17 + 971141 = 971158
47 + 971111 = 971158
59 + 971099 = 971158
107 + 971051 = 971158
131 + 971027 = 971158
137 + 971021 = 971158
191 + 970967 = 971158

Showing the first eight; more decompositions exist.
