Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584526, here are decompositions:

3 + 31584523 = 31584526
137 + 31584389 = 31584526
227 + 31584299 = 31584526
263 + 31584263 = 31584526
293 + 31584233 = 31584526
353 + 31584173 = 31584526
383 + 31584143 = 31584526
773 + 31583753 = 31584526

Showing the first eight; more decompositions exist.
