Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475614, here are decompositions:

3 + 31475611 = 31475614
17 + 31475597 = 31475614
227 + 31475387 = 31475614
293 + 31475321 = 31475614
383 + 31475231 = 31475614
503 + 31475111 = 31475614
617 + 31474997 = 31475614
683 + 31474931 = 31475614

Showing the first eight; more decompositions exist.
