Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584814, here are decompositions:

5 + 31584809 = 31584814
17 + 31584797 = 31584814
101 + 31584713 = 31584814
197 + 31584617 = 31584814
263 + 31584551 = 31584814
383 + 31584431 = 31584814
431 + 31584383 = 31584814
491 + 31584323 = 31584814

Showing the first eight; more decompositions exist.
