Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475464, here are decompositions:

5 + 31475459 = 31475464
11 + 31475453 = 31475464
71 + 31475393 = 31475464
233 + 31475231 = 31475464
353 + 31475111 = 31475464
467 + 31474997 = 31475464
701 + 31474763 = 31475464
743 + 31474721 = 31475464

Showing the first eight; more decompositions exist.
