Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514632, here are decompositions:

3 + 31514629 = 31514632
5 + 31514627 = 31514632
53 + 31514579 = 31514632
59 + 31514573 = 31514632
839 + 31513793 = 31514632
911 + 31513721 = 31514632
971 + 31513661 = 31514632
1019 + 31513613 = 31514632

Showing the first eight; more decompositions exist.
