Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584024, here are decompositions:

5 + 31584019 = 31584024
41 + 31583983 = 31584024
53 + 31583971 = 31584024
83 + 31583941 = 31584024
103 + 31583921 = 31584024
113 + 31583911 = 31584024
127 + 31583897 = 31584024
167 + 31583857 = 31584024

Showing the first eight; more decompositions exist.
