Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496310, here are decompositions:

17 + 31496293 = 31496310
47 + 31496263 = 31496310
89 + 31496221 = 31496310
101 + 31496209 = 31496310
137 + 31496173 = 31496310
149 + 31496161 = 31496310
191 + 31496119 = 31496310
211 + 31496099 = 31496310

Showing the first eight; more decompositions exist.
