Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586670, here are decompositions:

23 + 31586647 = 31586670
43 + 31586627 = 31586670
53 + 31586617 = 31586670
79 + 31586591 = 31586670
127 + 31586543 = 31586670
173 + 31586497 = 31586670
197 + 31586473 = 31586670
223 + 31586447 = 31586670

Showing the first eight; more decompositions exist.
