Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585056, here are decompositions:

23 + 31585033 = 31585056
37 + 31585019 = 31585056
89 + 31584967 = 31585056
103 + 31584953 = 31585056
109 + 31584947 = 31585056
149 + 31584907 = 31585056
227 + 31584829 = 31585056
233 + 31584823 = 31585056

Showing the first eight; more decompositions exist.
