Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584454, here are decompositions:

23 + 31584431 = 31584454
47 + 31584407 = 31584454
53 + 31584401 = 31584454
71 + 31584383 = 31584454
131 + 31584323 = 31584454
173 + 31584281 = 31584454
191 + 31584263 = 31584454
257 + 31584197 = 31584454

Showing the first eight; more decompositions exist.
