Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475676, here are decompositions:

7 + 31475669 = 31475676
53 + 31475623 = 31475676
79 + 31475597 = 31475676
97 + 31475579 = 31475676
223 + 31475453 = 31475676
233 + 31475443 = 31475676
269 + 31475407 = 31475676
283 + 31475393 = 31475676

Showing the first eight; more decompositions exist.
