Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516132, here are decompositions:

3 + 31516129 = 31516132
23 + 31516109 = 31516132
29 + 31516103 = 31516132
71 + 31516061 = 31516132
191 + 31515941 = 31516132
233 + 31515899 = 31516132
239 + 31515893 = 31516132
251 + 31515881 = 31516132

Showing the first eight; more decompositions exist.
