Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584328, here are decompositions:

5 + 31584323 = 31584328
29 + 31584299 = 31584328
47 + 31584281 = 31584328
131 + 31584197 = 31584328
137 + 31584191 = 31584328
227 + 31584101 = 31584328
431 + 31583897 = 31584328
491 + 31583837 = 31584328

Showing the first eight; more decompositions exist.
