Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475404, here are decompositions:

3 + 31475401 = 31475404
11 + 31475393 = 31475404
17 + 31475387 = 31475404
83 + 31475321 = 31475404
173 + 31475231 = 31475404
263 + 31475141 = 31475404
293 + 31475111 = 31475404
641 + 31474763 = 31475404

Showing the first eight; more decompositions exist.
