Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475412, here are decompositions:

5 + 31475407 = 31475412
11 + 31475401 = 31475412
19 + 31475393 = 31475412
41 + 31475371 = 31475412
71 + 31475341 = 31475412
181 + 31475231 = 31475412
223 + 31475189 = 31475412
271 + 31475141 = 31475412

Showing the first eight; more decompositions exist.
