Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584496, here are decompositions:

89 + 31584407 = 31584496
107 + 31584389 = 31584496
113 + 31584383 = 31584496
173 + 31584323 = 31584496
197 + 31584299 = 31584496
233 + 31584263 = 31584496
263 + 31584233 = 31584496
353 + 31584143 = 31584496

Showing the first eight; more decompositions exist.
