Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573032, here are decompositions:

5 + 31573027 = 31573032
11 + 31573021 = 31573032
53 + 31572979 = 31573032
61 + 31572971 = 31573032
83 + 31572949 = 31573032
89 + 31572943 = 31573032
131 + 31572901 = 31573032
151 + 31572881 = 31573032

Showing the first eight; more decompositions exist.
