Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475294, here are decompositions:

7 + 31475287 = 31475294
43 + 31475251 = 31475294
163 + 31475131 = 31475294
211 + 31475083 = 31475294
223 + 31475071 = 31475294
241 + 31475053 = 31475294
313 + 31474981 = 31475294
421 + 31474873 = 31475294

Showing the first eight; more decompositions exist.
