Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584584, here are decompositions:

7 + 31584577 = 31584584
37 + 31584547 = 31584584
43 + 31584541 = 31584584
61 + 31584523 = 31584584
103 + 31584481 = 31584584
127 + 31584457 = 31584584
211 + 31584373 = 31584584
223 + 31584361 = 31584584

Showing the first eight; more decompositions exist.
