Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482160, here are decompositions:

41 + 31482119 = 31482160
71 + 31482089 = 31482160
113 + 31482047 = 31482160
179 + 31481981 = 31482160
239 + 31481921 = 31482160
293 + 31481867 = 31482160
317 + 31481843 = 31482160
443 + 31481717 = 31482160

Showing the first eight; more decompositions exist.
