Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514922, here are decompositions:

11 + 31514911 = 31514922
29 + 31514893 = 31514922
53 + 31514869 = 31514922
73 + 31514849 = 31514922
83 + 31514839 = 31514922
139 + 31514783 = 31514922
151 + 31514771 = 31514922
181 + 31514741 = 31514922

Showing the first eight; more decompositions exist.
