Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584536, here are decompositions:

13 + 31584523 = 31584536
37 + 31584499 = 31584536
79 + 31584457 = 31584536
97 + 31584439 = 31584536
163 + 31584373 = 31584536
199 + 31584337 = 31584536
229 + 31584307 = 31584536
397 + 31584139 = 31584536

Showing the first eight; more decompositions exist.
