Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584544, here are decompositions:

3 + 31584541 = 31584544
113 + 31584431 = 31584544
137 + 31584407 = 31584544
263 + 31584281 = 31584544
281 + 31584263 = 31584544
311 + 31584233 = 31584544
347 + 31584197 = 31584544
353 + 31584191 = 31584544

Showing the first eight; more decompositions exist.
