Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584682, here are decompositions:

29 + 31584653 = 31584682
131 + 31584551 = 31584682
251 + 31584431 = 31584682
281 + 31584401 = 31584682
293 + 31584389 = 31584682
359 + 31584323 = 31584682
383 + 31584299 = 31584682
401 + 31584281 = 31584682

Showing the first eight; more decompositions exist.
