Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584444, here are decompositions:

5 + 31584439 = 31584444
13 + 31584431 = 31584444
37 + 31584407 = 31584444
43 + 31584401 = 31584444
61 + 31584383 = 31584444
71 + 31584373 = 31584444
83 + 31584361 = 31584444
107 + 31584337 = 31584444

Showing the first eight; more decompositions exist.
