Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570064, here are decompositions:

7 + 31570057 = 31570064
181 + 31569883 = 31570064
271 + 31569793 = 31570064
283 + 31569781 = 31570064
313 + 31569751 = 31570064
373 + 31569691 = 31570064
727 + 31569337 = 31570064
787 + 31569277 = 31570064

Showing the first eight; more decompositions exist.
