Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584718, here are decompositions:

5 + 31584713 = 31584718
29 + 31584689 = 31584718
101 + 31584617 = 31584718
167 + 31584551 = 31584718
311 + 31584407 = 31584718
317 + 31584401 = 31584718
419 + 31584299 = 31584718
521 + 31584197 = 31584718

Showing the first eight; more decompositions exist.
