Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584592, here are decompositions:

41 + 31584551 = 31584592
191 + 31584401 = 31584592
269 + 31584323 = 31584592
293 + 31584299 = 31584592
311 + 31584281 = 31584592
359 + 31584233 = 31584592
401 + 31584191 = 31584592
419 + 31584173 = 31584592

Showing the first eight; more decompositions exist.
