Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584944, here are decompositions:

37 + 31584907 = 31584944
43 + 31584901 = 31584944
241 + 31584703 = 31584944
277 + 31584667 = 31584944
331 + 31584613 = 31584944
337 + 31584607 = 31584944
367 + 31584577 = 31584944
397 + 31584547 = 31584944

Showing the first eight; more decompositions exist.
