Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584318, here are decompositions:

11 + 31584307 = 31584318
19 + 31584299 = 31584318
37 + 31584281 = 31584318
71 + 31584247 = 31584318
107 + 31584211 = 31584318
127 + 31584191 = 31584318
179 + 31584139 = 31584318
251 + 31584067 = 31584318

Showing the first eight; more decompositions exist.
