Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516804, here are decompositions:

17 + 31516787 = 31516804
23 + 31516781 = 31516804
47 + 31516757 = 31516804
101 + 31516703 = 31516804
107 + 31516697 = 31516804
173 + 31516631 = 31516804
191 + 31516613 = 31516804
233 + 31516571 = 31516804

Showing the first eight; more decompositions exist.
