Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585194, here are decompositions:

5 + 31585189 = 31585194
13 + 31585181 = 31585194
23 + 31585171 = 31585194
101 + 31585093 = 31585194
127 + 31585067 = 31585194
227 + 31584967 = 31585194
233 + 31584961 = 31585194
241 + 31584953 = 31585194

Showing the first eight; more decompositions exist.
