Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584736, here are decompositions:

23 + 31584713 = 31584736
47 + 31584689 = 31584736
83 + 31584653 = 31584736
347 + 31584389 = 31584736
353 + 31584383 = 31584736
503 + 31584233 = 31584736
563 + 31584173 = 31584736
593 + 31584143 = 31584736

Showing the first eight; more decompositions exist.
