Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516794, here are decompositions:

5 + 31516789 = 31516794
7 + 31516787 = 31516794
13 + 31516781 = 31516794
17 + 31516777 = 31516794
37 + 31516757 = 31516794
41 + 31516753 = 31516794
97 + 31516697 = 31516794
163 + 31516631 = 31516794

Showing the first eight; more decompositions exist.
