Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584832, here are decompositions:

3 + 31584829 = 31584832
23 + 31584809 = 31584832
179 + 31584653 = 31584832
281 + 31584551 = 31584832
401 + 31584431 = 31584832
431 + 31584401 = 31584832
443 + 31584389 = 31584832
449 + 31584383 = 31584832

Showing the first eight; more decompositions exist.
