Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586824, here are decompositions:

11 + 31586813 = 31586824
107 + 31586717 = 31586824
197 + 31586627 = 31586824
233 + 31586591 = 31586824
281 + 31586543 = 31586824
587 + 31586237 = 31586824
653 + 31586171 = 31586824
677 + 31586147 = 31586824

Showing the first eight; more decompositions exist.
