Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582332, here are decompositions:

11 + 31582321 = 31582332
13 + 31582319 = 31582332
83 + 31582249 = 31582332
139 + 31582193 = 31582332
149 + 31582183 = 31582332
211 + 31582121 = 31582332
239 + 31582093 = 31582332
283 + 31582049 = 31582332

Showing the first eight; more decompositions exist.
