Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482162, here are decompositions:

43 + 31482119 = 31482162
59 + 31482103 = 31482162
73 + 31482089 = 31482162
79 + 31482083 = 31482162
149 + 31482013 = 31482162
181 + 31481981 = 31482162
211 + 31481951 = 31482162
223 + 31481939 = 31482162

Showing the first eight; more decompositions exist.
