Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627032, here are decompositions:

5 + 31627027 = 31627032
53 + 31626979 = 31627032
89 + 31626943 = 31627032
139 + 31626893 = 31627032
149 + 31626883 = 31627032
163 + 31626869 = 31627032
191 + 31626841 = 31627032
193 + 31626839 = 31627032

Showing the first eight; more decompositions exist.
