Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584576, here are decompositions:

17 + 31584559 = 31584576
29 + 31584547 = 31584576
53 + 31584523 = 31584576
137 + 31584439 = 31584576
193 + 31584383 = 31584576
239 + 31584337 = 31584576
269 + 31584307 = 31584576
277 + 31584299 = 31584576

Showing the first eight; more decompositions exist.
