Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584664, here are decompositions:

11 + 31584653 = 31584664
47 + 31584617 = 31584664
113 + 31584551 = 31584664
233 + 31584431 = 31584664
257 + 31584407 = 31584664
263 + 31584401 = 31584664
281 + 31584383 = 31584664
383 + 31584281 = 31584664

Showing the first eight; more decompositions exist.
