Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573092, here are decompositions:

71 + 31573021 = 31573092
113 + 31572979 = 31573092
149 + 31572943 = 31573092
151 + 31572941 = 31573092
191 + 31572901 = 31573092
211 + 31572881 = 31573092
223 + 31572869 = 31573092
251 + 31572841 = 31573092

Showing the first eight; more decompositions exist.
