Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584550, here are decompositions:

3 + 31584547 = 31584550
149 + 31584401 = 31584550
167 + 31584383 = 31584550
227 + 31584323 = 31584550
251 + 31584299 = 31584550
269 + 31584281 = 31584550
317 + 31584233 = 31584550
353 + 31584197 = 31584550

Showing the first eight; more decompositions exist.
