Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465794, here are decompositions:

5 + 31465789 = 31465794
13 + 31465781 = 31465794
37 + 31465757 = 31465794
47 + 31465747 = 31465794
53 + 31465741 = 31465794
67 + 31465727 = 31465794
83 + 31465711 = 31465794
97 + 31465697 = 31465794

Showing the first eight; more decompositions exist.
