Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482, here are decompositions:

5 + 31477 = 31482
13 + 31469 = 31482
89 + 31393 = 31482
103 + 31379 = 31482
149 + 31333 = 31482
163 + 31319 = 31482
211 + 31271 = 31482
223 + 31259 = 31482

Showing the first eight; more decompositions exist.
