Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584646, here are decompositions:

29 + 31584617 = 31584646
239 + 31584407 = 31584646
257 + 31584389 = 31584646
263 + 31584383 = 31584646
347 + 31584299 = 31584646
383 + 31584263 = 31584646
449 + 31584197 = 31584646
503 + 31584143 = 31584646

Showing the first eight; more decompositions exist.
