Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570016, here are decompositions:

3 + 31570013 = 31570016
73 + 31569943 = 31570016
157 + 31569859 = 31570016
223 + 31569793 = 31570016
307 + 31569709 = 31570016
739 + 31569277 = 31570016
757 + 31569259 = 31570016
769 + 31569247 = 31570016

Showing the first eight; more decompositions exist.
