Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585846, here are decompositions:

23 + 31585823 = 31585846
29 + 31585817 = 31585846
179 + 31585667 = 31585846
197 + 31585649 = 31585846
233 + 31585613 = 31585846
263 + 31585583 = 31585846
269 + 31585577 = 31585846
317 + 31585529 = 31585846

Showing the first eight; more decompositions exist.
