Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461310, here are decompositions:

17 + 31461293 = 31461310
29 + 31461281 = 31461310
131 + 31461179 = 31461310
137 + 31461173 = 31461310
149 + 31461161 = 31461310
197 + 31461113 = 31461310
263 + 31461047 = 31461310
359 + 31460951 = 31461310

Showing the first eight; more decompositions exist.
