Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589676, here are decompositions:

17 + 31589659 = 31589676
43 + 31589633 = 31589676
109 + 31589567 = 31589676
137 + 31589539 = 31589676
163 + 31589513 = 31589676
193 + 31589483 = 31589676
269 + 31589407 = 31589676
317 + 31589359 = 31589676

Showing the first eight; more decompositions exist.
