Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586636, here are decompositions:

19 + 31586617 = 31586636
127 + 31586509 = 31586636
139 + 31586497 = 31586636
163 + 31586473 = 31586636
229 + 31586407 = 31586636
349 + 31586287 = 31586636
379 + 31586257 = 31586636
577 + 31586059 = 31586636

Showing the first eight; more decompositions exist.
