Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465896, here are decompositions:

5 + 31465891 = 31465896
17 + 31465879 = 31465896
47 + 31465849 = 31465896
67 + 31465829 = 31465896
107 + 31465789 = 31465896
139 + 31465757 = 31465896
149 + 31465747 = 31465896
199 + 31465697 = 31465896

Showing the first eight; more decompositions exist.
