Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584594, here are decompositions:

17 + 31584577 = 31584594
43 + 31584551 = 31584594
47 + 31584547 = 31584594
53 + 31584541 = 31584594
71 + 31584523 = 31584594
113 + 31584481 = 31584594
137 + 31584457 = 31584594
163 + 31584431 = 31584594

Showing the first eight; more decompositions exist.
