Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596404, here are decompositions:

3 + 31596401 = 31596404
13 + 31596391 = 31596404
97 + 31596307 = 31596404
211 + 31596193 = 31596404
241 + 31596163 = 31596404
277 + 31596127 = 31596404
283 + 31596121 = 31596404
337 + 31596067 = 31596404

Showing the first eight; more decompositions exist.
