Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584476, here are decompositions:

19 + 31584457 = 31584476
37 + 31584439 = 31584476
103 + 31584373 = 31584476
139 + 31584337 = 31584476
229 + 31584247 = 31584476
283 + 31584193 = 31584476
337 + 31584139 = 31584476
409 + 31584067 = 31584476

Showing the first eight; more decompositions exist.
