Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475354, here are decompositions:

13 + 31475341 = 31475354
37 + 31475317 = 31475354
67 + 31475287 = 31475354
103 + 31475251 = 31475354
223 + 31475131 = 31475354
271 + 31475083 = 31475354
283 + 31475071 = 31475354
373 + 31474981 = 31475354

Showing the first eight; more decompositions exist.
