Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483908, here are decompositions:

19 + 31483889 = 31483908
31 + 31483877 = 31483908
37 + 31483871 = 31483908
47 + 31483861 = 31483908
67 + 31483841 = 31483908
89 + 31483819 = 31483908
101 + 31483807 = 31483908
107 + 31483801 = 31483908

Showing the first eight; more decompositions exist.
