Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584484, here are decompositions:

3 + 31584481 = 31584484
53 + 31584431 = 31584484
83 + 31584401 = 31584484
101 + 31584383 = 31584484
251 + 31584233 = 31584484
293 + 31584191 = 31584484
311 + 31584173 = 31584484
383 + 31584101 = 31584484

Showing the first eight; more decompositions exist.
