Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585336, here are decompositions:

5 + 31585331 = 31585336
17 + 31585319 = 31585336
23 + 31585313 = 31585336
47 + 31585289 = 31585336
137 + 31585199 = 31585336
197 + 31585139 = 31585336
257 + 31585079 = 31585336
269 + 31585067 = 31585336

Showing the first eight; more decompositions exist.
