Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475310, here are decompositions:

23 + 31475287 = 31475310
59 + 31475251 = 31475310
67 + 31475243 = 31475310
79 + 31475231 = 31475310
101 + 31475209 = 31475310
151 + 31475159 = 31475310
179 + 31475131 = 31475310
199 + 31475111 = 31475310

Showing the first eight; more decompositions exist.
