Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584316, here are decompositions:

17 + 31584299 = 31584316
53 + 31584263 = 31584316
83 + 31584233 = 31584316
173 + 31584143 = 31584316
317 + 31583999 = 31584316
419 + 31583897 = 31584316
479 + 31583837 = 31584316
563 + 31583753 = 31584316

Showing the first eight; more decompositions exist.
