Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584354, here are decompositions:

17 + 31584337 = 31584354
31 + 31584323 = 31584354
47 + 31584307 = 31584354
73 + 31584281 = 31584354
107 + 31584247 = 31584354
157 + 31584197 = 31584354
163 + 31584191 = 31584354
181 + 31584173 = 31584354

Showing the first eight; more decompositions exist.
