Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514224, here are decompositions:

3 + 31514221 = 31514224
257 + 31513967 = 31514224
281 + 31513943 = 31514224
347 + 31513877 = 31514224
431 + 31513793 = 31514224
503 + 31513721 = 31514224
557 + 31513667 = 31514224
563 + 31513661 = 31514224

Showing the first eight; more decompositions exist.
