Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584360, here are decompositions:

23 + 31584337 = 31584360
37 + 31584323 = 31584360
53 + 31584307 = 31584360
61 + 31584299 = 31584360
79 + 31584281 = 31584360
97 + 31584263 = 31584360
113 + 31584247 = 31584360
127 + 31584233 = 31584360

Showing the first eight; more decompositions exist.
