Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597196, here are decompositions:

19 + 31597177 = 31597196
67 + 31597129 = 31597196
97 + 31597099 = 31597196
193 + 31597003 = 31597196
199 + 31596997 = 31597196
283 + 31596913 = 31597196
307 + 31596889 = 31597196
313 + 31596883 = 31597196

Showing the first eight; more decompositions exist.
