Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584468, here are decompositions:

11 + 31584457 = 31584468
29 + 31584439 = 31584468
37 + 31584431 = 31584468
61 + 31584407 = 31584468
67 + 31584401 = 31584468
79 + 31584389 = 31584468
107 + 31584361 = 31584468
131 + 31584337 = 31584468

Showing the first eight; more decompositions exist.
