Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475356, here are decompositions:

113 + 31475243 = 31475356
167 + 31475189 = 31475356
197 + 31475159 = 31475356
257 + 31475099 = 31475356
347 + 31475009 = 31475356
359 + 31474997 = 31475356
593 + 31474763 = 31475356
683 + 31474673 = 31475356

Showing the first eight; more decompositions exist.
