Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475298, here are decompositions:

11 + 31475287 = 31475298
47 + 31475251 = 31475298
67 + 31475231 = 31475298
89 + 31475209 = 31475298
109 + 31475189 = 31475298
139 + 31475159 = 31475298
157 + 31475141 = 31475298
167 + 31475131 = 31475298

Showing the first eight; more decompositions exist.
