Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584706, here are decompositions:

3 + 31584703 = 31584706
17 + 31584689 = 31584706
53 + 31584653 = 31584706
89 + 31584617 = 31584706
317 + 31584389 = 31584706
383 + 31584323 = 31584706
443 + 31584263 = 31584706
509 + 31584197 = 31584706

Showing the first eight; more decompositions exist.
