Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585534, here are decompositions:

5 + 31585529 = 31585534
17 + 31585517 = 31585534
41 + 31585493 = 31585534
83 + 31585451 = 31585534
173 + 31585361 = 31585534
191 + 31585343 = 31585534
263 + 31585271 = 31585534
317 + 31585217 = 31585534

Showing the first eight; more decompositions exist.
