Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600964, here are decompositions:

7 + 31600957 = 31600964
103 + 31600861 = 31600964
163 + 31600801 = 31600964
181 + 31600783 = 31600964
193 + 31600771 = 31600964
211 + 31600753 = 31600964
223 + 31600741 = 31600964
271 + 31600693 = 31600964

Showing the first eight; more decompositions exist.
