Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584586, here are decompositions:

179 + 31584407 = 31584586
197 + 31584389 = 31584586
263 + 31584323 = 31584586
353 + 31584233 = 31584586
389 + 31584197 = 31584586
443 + 31584143 = 31584586
587 + 31583999 = 31584586
809 + 31583777 = 31584586

Showing the first eight; more decompositions exist.
