Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584324, here are decompositions:

17 + 31584307 = 31584324
43 + 31584281 = 31584324
61 + 31584263 = 31584324
113 + 31584211 = 31584324
127 + 31584197 = 31584324
131 + 31584193 = 31584324
151 + 31584173 = 31584324
181 + 31584143 = 31584324

Showing the first eight; more decompositions exist.
