Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584658, here are decompositions:

5 + 31584653 = 31584658
41 + 31584617 = 31584658
107 + 31584551 = 31584658
227 + 31584431 = 31584658
251 + 31584407 = 31584658
257 + 31584401 = 31584658
269 + 31584389 = 31584658
359 + 31584299 = 31584658

Showing the first eight; more decompositions exist.
