Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570032, here are decompositions:

19 + 31570013 = 31570032
79 + 31569953 = 31570032
89 + 31569943 = 31570032
149 + 31569883 = 31570032
173 + 31569859 = 31570032
181 + 31569851 = 31570032
239 + 31569793 = 31570032
251 + 31569781 = 31570032

Showing the first eight; more decompositions exist.
