Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602072, here are decompositions:

23 + 31602049 = 31602072
31 + 31602041 = 31602072
149 + 31601923 = 31602072
181 + 31601891 = 31602072
191 + 31601881 = 31602072
199 + 31601873 = 31602072
223 + 31601849 = 31602072
263 + 31601809 = 31602072

Showing the first eight; more decompositions exist.
