Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597232, here are decompositions:

19 + 31597213 = 31597232
103 + 31597129 = 31597232
151 + 31597081 = 31597232
181 + 31597051 = 31597232
229 + 31597003 = 31597232
241 + 31596991 = 31597232
283 + 31596949 = 31597232
349 + 31596883 = 31597232

Showing the first eight; more decompositions exist.
