Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582284, here are decompositions:

17 + 31582267 = 31582284
43 + 31582241 = 31582284
67 + 31582217 = 31582284
101 + 31582183 = 31582284
113 + 31582171 = 31582284
163 + 31582121 = 31582284
191 + 31582093 = 31582284
241 + 31582043 = 31582284

Showing the first eight; more decompositions exist.
