Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514946, here are decompositions:

13 + 31514933 = 31514946
53 + 31514893 = 31514946
97 + 31514849 = 31514946
107 + 31514839 = 31514946
109 + 31514837 = 31514946
157 + 31514789 = 31514946
163 + 31514783 = 31514946
257 + 31514689 = 31514946

Showing the first eight; more decompositions exist.
