Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584486, here are decompositions:

5 + 31584481 = 31584486
29 + 31584457 = 31584486
47 + 31584439 = 31584486
79 + 31584407 = 31584486
97 + 31584389 = 31584486
103 + 31584383 = 31584486
113 + 31584373 = 31584486
149 + 31584337 = 31584486

Showing the first eight; more decompositions exist.
