Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584766, here are decompositions:

53 + 31584713 = 31584766
113 + 31584653 = 31584766
149 + 31584617 = 31584766
359 + 31584407 = 31584766
383 + 31584383 = 31584766
443 + 31584323 = 31584766
467 + 31584299 = 31584766
503 + 31584263 = 31584766

Showing the first eight; more decompositions exist.
