Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584548, here are decompositions:

7 + 31584541 = 31584548
67 + 31584481 = 31584548
109 + 31584439 = 31584548
211 + 31584337 = 31584548
241 + 31584307 = 31584548
337 + 31584211 = 31584548
409 + 31584139 = 31584548
577 + 31583971 = 31584548

Showing the first eight; more decompositions exist.
