Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514910, here are decompositions:

17 + 31514893 = 31514910
41 + 31514869 = 31514910
61 + 31514849 = 31514910
71 + 31514839 = 31514910
73 + 31514837 = 31514910
127 + 31514783 = 31514910
139 + 31514771 = 31514910
179 + 31514731 = 31514910

Showing the first eight; more decompositions exist.
