Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514952, here are decompositions:

5 + 31514947 = 31514952
19 + 31514933 = 31514952
41 + 31514911 = 31514952
59 + 31514893 = 31514952
83 + 31514869 = 31514952
103 + 31514849 = 31514952
113 + 31514839 = 31514952
163 + 31514789 = 31514952

Showing the first eight; more decompositions exist.
