Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565694, here are decompositions:

23 + 31565671 = 31565694
31 + 31565663 = 31565694
197 + 31565497 = 31565694
233 + 31565461 = 31565694
257 + 31565437 = 31565694
263 + 31565431 = 31565694
271 + 31565423 = 31565694
283 + 31565411 = 31565694

Showing the first eight; more decompositions exist.
