Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475896, here are decompositions:

47 + 31475849 = 31475896
83 + 31475813 = 31475896
227 + 31475669 = 31475896
317 + 31475579 = 31475896
443 + 31475453 = 31475896
467 + 31475429 = 31475896
503 + 31475393 = 31475896
509 + 31475387 = 31475896

Showing the first eight; more decompositions exist.
