Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475410, here are decompositions:

3 + 31475407 = 31475410
17 + 31475393 = 31475410
23 + 31475387 = 31475410
89 + 31475321 = 31475410
167 + 31475243 = 31475410
179 + 31475231 = 31475410
251 + 31475159 = 31475410
269 + 31475141 = 31475410

Showing the first eight; more decompositions exist.
