Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483944, here are decompositions:

17 + 31483927 = 31483944
31 + 31483913 = 31483944
61 + 31483883 = 31483944
67 + 31483877 = 31483944
73 + 31483871 = 31483944
83 + 31483861 = 31483944
103 + 31483841 = 31483944
137 + 31483807 = 31483944

Showing the first eight; more decompositions exist.
