Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570026, here are decompositions:

13 + 31570013 = 31570026
43 + 31569983 = 31570026
73 + 31569953 = 31570026
83 + 31569943 = 31570026
167 + 31569859 = 31570026
197 + 31569829 = 31570026
233 + 31569793 = 31570026
263 + 31569763 = 31570026

Showing the first eight; more decompositions exist.
