Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585492, here are decompositions:

23 + 31585469 = 31585492
41 + 31585451 = 31585492
131 + 31585361 = 31585492
149 + 31585343 = 31585492
173 + 31585319 = 31585492
179 + 31585313 = 31585492
293 + 31585199 = 31585492
311 + 31585181 = 31585492

Showing the first eight; more decompositions exist.
