Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482118, here are decompositions:

29 + 31482089 = 31482118
71 + 31482047 = 31482118
137 + 31481981 = 31482118
167 + 31481951 = 31482118
179 + 31481939 = 31482118
197 + 31481921 = 31482118
251 + 31481867 = 31482118
281 + 31481837 = 31482118

Showing the first eight; more decompositions exist.
