Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584268, here are decompositions:

5 + 31584263 = 31584268
71 + 31584197 = 31584268
167 + 31584101 = 31584268
269 + 31583999 = 31584268
347 + 31583921 = 31584268
431 + 31583837 = 31584268
449 + 31583819 = 31584268
491 + 31583777 = 31584268

Showing the first eight; more decompositions exist.
