Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597352, here are decompositions:

109 + 31597243 = 31597352
139 + 31597213 = 31597352
223 + 31597129 = 31597352
271 + 31597081 = 31597352
349 + 31597003 = 31597352
439 + 31596913 = 31597352
463 + 31596889 = 31597352
601 + 31596751 = 31597352

Showing the first eight; more decompositions exist.
