Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584712, here are decompositions:

23 + 31584689 = 31584712
59 + 31584653 = 31584712
281 + 31584431 = 31584712
311 + 31584401 = 31584712
389 + 31584323 = 31584712
431 + 31584281 = 31584712
449 + 31584263 = 31584712
479 + 31584233 = 31584712

Showing the first eight; more decompositions exist.
