Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584494, here are decompositions:

13 + 31584481 = 31584494
37 + 31584457 = 31584494
157 + 31584337 = 31584494
283 + 31584211 = 31584494
523 + 31583971 = 31584494
631 + 31583863 = 31584494
691 + 31583803 = 31584494
853 + 31583641 = 31584494

Showing the first eight; more decompositions exist.
