Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494310, here are decompositions:

17 + 31494293 = 31494310
47 + 31494263 = 31494310
53 + 31494257 = 31494310
131 + 31494179 = 31494310
149 + 31494161 = 31494310
167 + 31494143 = 31494310
191 + 31494119 = 31494310
227 + 31494083 = 31494310

Showing the first eight; more decompositions exist.
