Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482130, here are decompositions:

11 + 31482119 = 31482130
41 + 31482089 = 31482130
47 + 31482083 = 31482130
83 + 31482047 = 31482130
89 + 31482041 = 31482130
149 + 31481981 = 31482130
179 + 31481951 = 31482130
191 + 31481939 = 31482130

Showing the first eight; more decompositions exist.
