Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584934, here are decompositions:

47 + 31584887 = 31584934
53 + 31584881 = 31584934
137 + 31584797 = 31584934
281 + 31584653 = 31584934
317 + 31584617 = 31584934
383 + 31584551 = 31584934
503 + 31584431 = 31584934
653 + 31584281 = 31584934

Showing the first eight; more decompositions exist.
