Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586634, here are decompositions:

7 + 31586627 = 31586634
17 + 31586617 = 31586634
43 + 31586591 = 31586634
97 + 31586537 = 31586634
137 + 31586497 = 31586634
151 + 31586483 = 31586634
173 + 31586461 = 31586634
227 + 31586407 = 31586634

Showing the first eight; more decompositions exist.
