Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496928, here are decompositions:

7 + 31496921 = 31496928
11 + 31496917 = 31496928
101 + 31496827 = 31496928
109 + 31496819 = 31496928
137 + 31496791 = 31496928
149 + 31496779 = 31496928
251 + 31496677 = 31496928
257 + 31496671 = 31496928

Showing the first eight; more decompositions exist.
