Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584112, here are decompositions:

11 + 31584101 = 31584112
113 + 31583999 = 31584112
191 + 31583921 = 31584112
281 + 31583831 = 31584112
293 + 31583819 = 31584112
359 + 31583753 = 31584112
383 + 31583729 = 31584112
419 + 31583693 = 31584112

Showing the first eight; more decompositions exist.
