Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584562, here are decompositions:

3 + 31584559 = 31584562
11 + 31584551 = 31584562
131 + 31584431 = 31584562
173 + 31584389 = 31584562
179 + 31584383 = 31584562
239 + 31584323 = 31584562
263 + 31584299 = 31584562
281 + 31584281 = 31584562

Showing the first eight; more decompositions exist.
