Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597066, here are decompositions:

23 + 31597043 = 31597066
89 + 31596977 = 31597066
167 + 31596899 = 31597066
227 + 31596839 = 31597066
269 + 31596797 = 31597066
317 + 31596749 = 31597066
353 + 31596713 = 31597066
359 + 31596707 = 31597066

Showing the first eight; more decompositions exist.
