Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597270, here are decompositions:

17 + 31597253 = 31597270
71 + 31597199 = 31597270
149 + 31597121 = 31597270
227 + 31597043 = 31597270
239 + 31597031 = 31597270
293 + 31596977 = 31597270
347 + 31596923 = 31597270
389 + 31596881 = 31597270

Showing the first eight; more decompositions exist.
