Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589634, here are decompositions:

23 + 31589611 = 31589634
67 + 31589567 = 31589634
73 + 31589561 = 31589634
151 + 31589483 = 31589634
173 + 31589461 = 31589634
211 + 31589423 = 31589634
227 + 31589407 = 31589634
233 + 31589401 = 31589634

Showing the first eight; more decompositions exist.
