Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584406, here are decompositions:

5 + 31584401 = 31584406
17 + 31584389 = 31584406
23 + 31584383 = 31584406
83 + 31584323 = 31584406
107 + 31584299 = 31584406
173 + 31584233 = 31584406
233 + 31584173 = 31584406
263 + 31584143 = 31584406

Showing the first eight; more decompositions exist.
