Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584762, here are decompositions:

5 + 31584757 = 31584762
59 + 31584703 = 31584762
73 + 31584689 = 31584762
109 + 31584653 = 31584762
149 + 31584613 = 31584762
211 + 31584551 = 31584762
239 + 31584523 = 31584762
263 + 31584499 = 31584762

Showing the first eight; more decompositions exist.
