Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586526, here are decompositions:

17 + 31586509 = 31586526
29 + 31586497 = 31586526
43 + 31586483 = 31586526
53 + 31586473 = 31586526
79 + 31586447 = 31586526
149 + 31586377 = 31586526
239 + 31586287 = 31586526
269 + 31586257 = 31586526

Showing the first eight; more decompositions exist.
