Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597262, here are decompositions:

19 + 31597243 = 31597262
31 + 31597231 = 31597262
163 + 31597099 = 31597262
181 + 31597081 = 31597262
211 + 31597051 = 31597262
271 + 31596991 = 31597262
313 + 31596949 = 31597262
349 + 31596913 = 31597262

Showing the first eight; more decompositions exist.
