Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584822, here are decompositions:

13 + 31584809 = 31584822
53 + 31584769 = 31584822
109 + 31584713 = 31584822
263 + 31584559 = 31584822
271 + 31584551 = 31584822
281 + 31584541 = 31584822
383 + 31584439 = 31584822
421 + 31584401 = 31584822

Showing the first eight; more decompositions exist.
