Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584844, here are decompositions:

47 + 31584797 = 31584844
131 + 31584713 = 31584844
191 + 31584653 = 31584844
227 + 31584617 = 31584844
293 + 31584551 = 31584844
443 + 31584401 = 31584844
461 + 31584383 = 31584844
521 + 31584323 = 31584844

Showing the first eight; more decompositions exist.
