Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475046, here are decompositions:

17 + 31475029 = 31475046
37 + 31475009 = 31475046
47 + 31474999 = 31475046
173 + 31474873 = 31475046
179 + 31474867 = 31475046
263 + 31474783 = 31475046
269 + 31474777 = 31475046
283 + 31474763 = 31475046

Showing the first eight; more decompositions exist.
