Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570052, here are decompositions:

109 + 31569943 = 31570052
193 + 31569859 = 31570052
223 + 31569829 = 31570052
271 + 31569781 = 31570052
439 + 31569613 = 31570052
571 + 31569481 = 31570052
673 + 31569379 = 31570052
733 + 31569319 = 31570052

Showing the first eight; more decompositions exist.
