Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514164, here are decompositions:

5 + 31514159 = 31514164
83 + 31514081 = 31514164
197 + 31513967 = 31514164
347 + 31513817 = 31514164
443 + 31513721 = 31514164
467 + 31513697 = 31514164
503 + 31513661 = 31514164
557 + 31513607 = 31514164

Showing the first eight; more decompositions exist.
