Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589586, here are decompositions:

19 + 31589567 = 31589586
47 + 31589539 = 31589586
73 + 31589513 = 31589586
103 + 31589483 = 31589586
113 + 31589473 = 31589586
163 + 31589423 = 31589586
179 + 31589407 = 31589586
227 + 31589359 = 31589586

Showing the first eight; more decompositions exist.
