Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475422, here are decompositions:

29 + 31475393 = 31475422
101 + 31475321 = 31475422
179 + 31475243 = 31475422
191 + 31475231 = 31475422
233 + 31475189 = 31475422
263 + 31475159 = 31475422
281 + 31475141 = 31475422
311 + 31475111 = 31475422

Showing the first eight; more decompositions exist.
