Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584298, here are decompositions:

17 + 31584281 = 31584298
101 + 31584197 = 31584298
107 + 31584191 = 31584298
197 + 31584101 = 31584298
401 + 31583897 = 31584298
461 + 31583837 = 31584298
467 + 31583831 = 31584298
479 + 31583819 = 31584298

Showing the first eight; more decompositions exist.
