Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585546, here are decompositions:

17 + 31585529 = 31585546
29 + 31585517 = 31585546
53 + 31585493 = 31585546
227 + 31585319 = 31585546
233 + 31585313 = 31585546
257 + 31585289 = 31585546
347 + 31585199 = 31585546
353 + 31585193 = 31585546

Showing the first eight; more decompositions exist.
