Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584574, here are decompositions:

23 + 31584551 = 31584574
167 + 31584407 = 31584574
173 + 31584401 = 31584574
191 + 31584383 = 31584574
251 + 31584323 = 31584574
293 + 31584281 = 31584574
311 + 31584263 = 31584574
383 + 31584191 = 31584574

Showing the first eight; more decompositions exist.
