Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585834, here are decompositions:

11 + 31585823 = 31585834
17 + 31585817 = 31585834
23 + 31585811 = 31585834
53 + 31585781 = 31585834
83 + 31585751 = 31585834
167 + 31585667 = 31585834
197 + 31585637 = 31585834
251 + 31585583 = 31585834

Showing the first eight; more decompositions exist.
