Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586622, here are decompositions:

5 + 31586617 = 31586622
31 + 31586591 = 31586622
43 + 31586579 = 31586622
79 + 31586543 = 31586622
113 + 31586509 = 31586622
139 + 31586483 = 31586622
149 + 31586473 = 31586622
271 + 31586351 = 31586622

Showing the first eight; more decompositions exist.
