Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570996, here are decompositions:

3 + 31570993 = 31570996
47 + 31570949 = 31570996
89 + 31570907 = 31570996
137 + 31570859 = 31570996
167 + 31570829 = 31570996
179 + 31570817 = 31570996
239 + 31570757 = 31570996
383 + 31570613 = 31570996

Showing the first eight; more decompositions exist.
