Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622070, here are decompositions:

23 + 31622047 = 31622070
89 + 31621981 = 31622070
107 + 31621963 = 31622070
113 + 31621957 = 31622070
173 + 31621897 = 31622070
191 + 31621879 = 31622070
223 + 31621847 = 31622070
239 + 31621831 = 31622070

Showing the first eight; more decompositions exist.
