Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573052, here are decompositions:

31 + 31573021 = 31573052
73 + 31572979 = 31573052
103 + 31572949 = 31573052
109 + 31572943 = 31573052
151 + 31572901 = 31573052
211 + 31572841 = 31573052
229 + 31572823 = 31573052
283 + 31572769 = 31573052

Showing the first eight; more decompositions exist.
