Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496916, here are decompositions:

43 + 31496873 = 31496916
53 + 31496863 = 31496916
89 + 31496827 = 31496916
97 + 31496819 = 31496916
107 + 31496809 = 31496916
137 + 31496779 = 31496916
197 + 31496719 = 31496916
223 + 31496693 = 31496916

Showing the first eight; more decompositions exist.
