Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475254, here are decompositions:

3 + 31475251 = 31475254
11 + 31475243 = 31475254
23 + 31475231 = 31475254
113 + 31475141 = 31475254
257 + 31474997 = 31475254
491 + 31474763 = 31475254
521 + 31474733 = 31475254
563 + 31474691 = 31475254

Showing the first eight; more decompositions exist.
