Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475846, here are decompositions:

19 + 31475827 = 31475846
67 + 31475779 = 31475846
97 + 31475749 = 31475846
163 + 31475683 = 31475846
223 + 31475623 = 31475846
439 + 31475407 = 31475846
739 + 31475107 = 31475846
757 + 31475089 = 31475846

Showing the first eight; more decompositions exist.
