Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584552, here are decompositions:

5 + 31584547 = 31584552
11 + 31584541 = 31584552
29 + 31584523 = 31584552
53 + 31584499 = 31584552
71 + 31584481 = 31584552
113 + 31584439 = 31584552
151 + 31584401 = 31584552
163 + 31584389 = 31584552

Showing the first eight; more decompositions exist.
