Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570036, here are decompositions:

23 + 31570013 = 31570036
53 + 31569983 = 31570036
59 + 31569977 = 31570036
83 + 31569953 = 31570036
269 + 31569767 = 31570036
347 + 31569689 = 31570036
389 + 31569647 = 31570036
419 + 31569617 = 31570036

Showing the first eight; more decompositions exist.
