Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516896, here are decompositions:

7 + 31516889 = 31516896
17 + 31516879 = 31516896
107 + 31516789 = 31516896
109 + 31516787 = 31516896
139 + 31516757 = 31516896
167 + 31516729 = 31516896
193 + 31516703 = 31516896
197 + 31516699 = 31516896

Showing the first eight; more decompositions exist.
