Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482016, here are decompositions:

3 + 31482013 = 31482016
149 + 31481867 = 31482016
173 + 31481843 = 31482016
179 + 31481837 = 31482016
197 + 31481819 = 31482016
263 + 31481753 = 31482016
509 + 31481507 = 31482016
557 + 31481459 = 31482016

Showing the first eight; more decompositions exist.
