Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496960, here are decompositions:

3 + 31496957 = 31496960
13 + 31496947 = 31496960
43 + 31496917 = 31496960
97 + 31496863 = 31496960
151 + 31496809 = 31496960
181 + 31496779 = 31496960
241 + 31496719 = 31496960
283 + 31496677 = 31496960

Showing the first eight; more decompositions exist.
