Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584334, here are decompositions:

11 + 31584323 = 31584334
53 + 31584281 = 31584334
71 + 31584263 = 31584334
101 + 31584233 = 31584334
137 + 31584197 = 31584334
191 + 31584143 = 31584334
233 + 31584101 = 31584334
503 + 31583831 = 31584334

Showing the first eight; more decompositions exist.
