Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475304, here are decompositions:

17 + 31475287 = 31475304
53 + 31475251 = 31475304
61 + 31475243 = 31475304
73 + 31475231 = 31475304
163 + 31475141 = 31475304
173 + 31475131 = 31475304
193 + 31475111 = 31475304
197 + 31475107 = 31475304

Showing the first eight; more decompositions exist.
