Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597164, here are decompositions:

13 + 31597151 = 31597164
37 + 31597127 = 31597164
43 + 31597121 = 31597164
83 + 31597081 = 31597164
113 + 31597051 = 31597164
167 + 31596997 = 31597164
173 + 31596991 = 31597164
241 + 31596923 = 31597164

Showing the first eight; more decompositions exist.
