Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584588, here are decompositions:

11 + 31584577 = 31584588
29 + 31584559 = 31584588
37 + 31584551 = 31584588
41 + 31584547 = 31584588
47 + 31584541 = 31584588
89 + 31584499 = 31584588
107 + 31584481 = 31584588
131 + 31584457 = 31584588

Showing the first eight; more decompositions exist.
