Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470934, here are decompositions:

17 + 31470917 = 31470934
23 + 31470911 = 31470934
71 + 31470863 = 31470934
101 + 31470833 = 31470934
107 + 31470827 = 31470934
233 + 31470701 = 31470934
281 + 31470653 = 31470934
293 + 31470641 = 31470934

Showing the first eight; more decompositions exist.
