Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622112, here are decompositions:

31 + 31622081 = 31622112
131 + 31621981 = 31622112
149 + 31621963 = 31622112
163 + 31621949 = 31622112
211 + 31621901 = 31622112
233 + 31621879 = 31622112
281 + 31621831 = 31622112
359 + 31621753 = 31622112

Showing the first eight; more decompositions exist.
