Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597192, here are decompositions:

41 + 31597151 = 31597192
71 + 31597121 = 31597192
149 + 31597043 = 31597192
269 + 31596923 = 31597192
293 + 31596899 = 31597192
311 + 31596881 = 31597192
353 + 31596839 = 31597192
443 + 31596749 = 31597192

Showing the first eight; more decompositions exist.
