Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514928, here are decompositions:

17 + 31514911 = 31514928
59 + 31514869 = 31514928
79 + 31514849 = 31514928
89 + 31514839 = 31514928
139 + 31514789 = 31514928
157 + 31514771 = 31514928
197 + 31514731 = 31514928
239 + 31514689 = 31514928

Showing the first eight; more decompositions exist.
