Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482136, here are decompositions:

17 + 31482119 = 31482136
47 + 31482089 = 31482136
53 + 31482083 = 31482136
89 + 31482047 = 31482136
197 + 31481939 = 31482136
269 + 31481867 = 31482136
293 + 31481843 = 31482136
317 + 31481819 = 31482136

Showing the first eight; more decompositions exist.
