Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585134, here are decompositions:

41 + 31585093 = 31585134
67 + 31585067 = 31585134
73 + 31585061 = 31585134
101 + 31585033 = 31585134
167 + 31584967 = 31585134
173 + 31584961 = 31585134
181 + 31584953 = 31585134
227 + 31584907 = 31585134

Showing the first eight; more decompositions exist.
