Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586696, here are decompositions:

7 + 31586689 = 31586696
79 + 31586617 = 31586696
199 + 31586497 = 31586696
223 + 31586473 = 31586696
409 + 31586287 = 31586696
439 + 31586257 = 31586696
619 + 31586077 = 31586696
643 + 31586053 = 31586696

Showing the first eight; more decompositions exist.
