Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584192, here are decompositions:

19 + 31584173 = 31584192
53 + 31584139 = 31584192
149 + 31584043 = 31584192
173 + 31584019 = 31584192
193 + 31583999 = 31584192
251 + 31583941 = 31584192
271 + 31583921 = 31584192
281 + 31583911 = 31584192

Showing the first eight; more decompositions exist.
