Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585322, here are decompositions:

3 + 31585319 = 31585322
61 + 31585261 = 31585322
151 + 31585171 = 31585322
163 + 31585159 = 31585322
229 + 31585093 = 31585322
421 + 31584901 = 31585322
499 + 31584823 = 31585322
619 + 31584703 = 31585322

Showing the first eight; more decompositions exist.
