Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597348, here are decompositions:

11 + 31597337 = 31597348
149 + 31597199 = 31597348
197 + 31597151 = 31597348
227 + 31597121 = 31597348
317 + 31597031 = 31597348
449 + 31596899 = 31597348
467 + 31596881 = 31597348
491 + 31596857 = 31597348

Showing the first eight; more decompositions exist.
