Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597112, here are decompositions:

13 + 31597099 = 31597112
31 + 31597081 = 31597112
61 + 31597051 = 31597112
109 + 31597003 = 31597112
163 + 31596949 = 31597112
199 + 31596913 = 31597112
223 + 31596889 = 31597112
229 + 31596883 = 31597112

Showing the first eight; more decompositions exist.
