Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589556, here are decompositions:

17 + 31589539 = 31589556
43 + 31589513 = 31589556
73 + 31589483 = 31589556
83 + 31589473 = 31589556
149 + 31589407 = 31589556
179 + 31589377 = 31589556
197 + 31589359 = 31589556
223 + 31589333 = 31589556

Showing the first eight; more decompositions exist.
