Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584382, here are decompositions:

59 + 31584323 = 31584382
83 + 31584299 = 31584382
101 + 31584281 = 31584382
149 + 31584233 = 31584382
191 + 31584191 = 31584382
239 + 31584143 = 31584382
281 + 31584101 = 31584382
383 + 31583999 = 31584382

Showing the first eight; more decompositions exist.
