Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584416, here are decompositions:

43 + 31584373 = 31584416
79 + 31584337 = 31584416
109 + 31584307 = 31584416
223 + 31584193 = 31584416
277 + 31584139 = 31584416
349 + 31584067 = 31584416
373 + 31584043 = 31584416
397 + 31584019 = 31584416

Showing the first eight; more decompositions exist.
