Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570056, here are decompositions:

13 + 31570043 = 31570056
43 + 31570013 = 31570056
73 + 31569983 = 31570056
79 + 31569977 = 31570056
103 + 31569953 = 31570056
113 + 31569943 = 31570056
173 + 31569883 = 31570056
197 + 31569859 = 31570056

Showing the first eight; more decompositions exist.
