Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584436, here are decompositions:

5 + 31584431 = 31584436
29 + 31584407 = 31584436
47 + 31584389 = 31584436
53 + 31584383 = 31584436
113 + 31584323 = 31584436
137 + 31584299 = 31584436
173 + 31584263 = 31584436
239 + 31584197 = 31584436

Showing the first eight; more decompositions exist.
