Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572050, here are decompositions:

43 + 31572007 = 31572050
67 + 31571983 = 31572050
151 + 31571899 = 31572050
163 + 31571887 = 31572050
229 + 31571821 = 31572050
241 + 31571809 = 31572050
271 + 31571779 = 31572050
397 + 31571653 = 31572050

Showing the first eight; more decompositions exist.
