Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584556, here are decompositions:

5 + 31584551 = 31584556
149 + 31584407 = 31584556
167 + 31584389 = 31584556
173 + 31584383 = 31584556
233 + 31584323 = 31584556
257 + 31584299 = 31584556
293 + 31584263 = 31584556
359 + 31584197 = 31584556

Showing the first eight; more decompositions exist.
