Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584952, here are decompositions:

5 + 31584947 = 31584952
71 + 31584881 = 31584952
83 + 31584869 = 31584952
239 + 31584713 = 31584952
263 + 31584689 = 31584952
401 + 31584551 = 31584952
521 + 31584431 = 31584952
563 + 31584389 = 31584952

Showing the first eight; more decompositions exist.
