Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483896, here are decompositions:

7 + 31483889 = 31483896
13 + 31483883 = 31483896
19 + 31483877 = 31483896
89 + 31483807 = 31483896
97 + 31483799 = 31483896
107 + 31483789 = 31483896
137 + 31483759 = 31483896
163 + 31483733 = 31483896

Showing the first eight; more decompositions exist.
