Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585588, here are decompositions:

5 + 31585583 = 31585588
11 + 31585577 = 31585588
17 + 31585571 = 31585588
59 + 31585529 = 31585588
71 + 31585517 = 31585588
137 + 31585451 = 31585588
227 + 31585361 = 31585588
257 + 31585331 = 31585588

Showing the first eight; more decompositions exist.
