Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585606, here are decompositions:

23 + 31585583 = 31585606
29 + 31585577 = 31585606
89 + 31585517 = 31585606
113 + 31585493 = 31585606
137 + 31585469 = 31585606
263 + 31585343 = 31585606
293 + 31585313 = 31585606
317 + 31585289 = 31585606

Showing the first eight; more decompositions exist.
