Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585582, here are decompositions:

3 + 31585579 = 31585582
5 + 31585577 = 31585582
11 + 31585571 = 31585582
53 + 31585529 = 31585582
89 + 31585493 = 31585582
113 + 31585469 = 31585582
131 + 31585451 = 31585582
239 + 31585343 = 31585582

Showing the first eight; more decompositions exist.
