Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584598, here are decompositions:

47 + 31584551 = 31584598
167 + 31584431 = 31584598
191 + 31584407 = 31584598
197 + 31584401 = 31584598
317 + 31584281 = 31584598
401 + 31584197 = 31584598
599 + 31583999 = 31584598
677 + 31583921 = 31584598

Showing the first eight; more decompositions exist.
