Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584366, here are decompositions:

5 + 31584361 = 31584366
29 + 31584337 = 31584366
43 + 31584323 = 31584366
59 + 31584307 = 31584366
67 + 31584299 = 31584366
103 + 31584263 = 31584366
173 + 31584193 = 31584366
193 + 31584173 = 31584366

Showing the first eight; more decompositions exist.
