Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516252, here are decompositions:

11 + 31516241 = 31516252
113 + 31516139 = 31516252
149 + 31516103 = 31516252
191 + 31516061 = 31516252
263 + 31515989 = 31516252
311 + 31515941 = 31516252
353 + 31515899 = 31516252
359 + 31515893 = 31516252

Showing the first eight; more decompositions exist.
