Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584694, here are decompositions:

5 + 31584689 = 31584694
41 + 31584653 = 31584694
263 + 31584431 = 31584694
293 + 31584401 = 31584694
311 + 31584383 = 31584694
431 + 31584263 = 31584694
461 + 31584233 = 31584694
503 + 31584191 = 31584694

Showing the first eight; more decompositions exist.
