Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584754, here are decompositions:

41 + 31584713 = 31584754
101 + 31584653 = 31584754
137 + 31584617 = 31584754
347 + 31584407 = 31584754
353 + 31584401 = 31584754
431 + 31584323 = 31584754
491 + 31584263 = 31584754
521 + 31584233 = 31584754

Showing the first eight; more decompositions exist.
