Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584432, here are decompositions:

31 + 31584401 = 31584432
43 + 31584389 = 31584432
59 + 31584373 = 31584432
71 + 31584361 = 31584432
109 + 31584323 = 31584432
151 + 31584281 = 31584432
199 + 31584233 = 31584432
239 + 31584193 = 31584432

Showing the first eight; more decompositions exist.
