Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582522, here are decompositions:

113 + 31582409 = 31582522
281 + 31582241 = 31582522
359 + 31582163 = 31582522
401 + 31582121 = 31582522
479 + 31582043 = 31582522
641 + 31581881 = 31582522
659 + 31581863 = 31582522
743 + 31581779 = 31582522

Showing the first eight; more decompositions exist.
