Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585234, here are decompositions:

17 + 31585217 = 31585234
41 + 31585193 = 31585234
53 + 31585181 = 31585234
167 + 31585067 = 31585234
173 + 31585061 = 31585234
281 + 31584953 = 31585234
347 + 31584887 = 31585234
353 + 31584881 = 31585234

Showing the first eight; more decompositions exist.
