Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584506, here are decompositions:

7 + 31584499 = 31584506
67 + 31584439 = 31584506
199 + 31584307 = 31584506
313 + 31584193 = 31584506
367 + 31584139 = 31584506
439 + 31584067 = 31584506
463 + 31584043 = 31584506
487 + 31584019 = 31584506

Showing the first eight; more decompositions exist.
