Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584050, here are decompositions:

7 + 31584043 = 31584050
31 + 31584019 = 31584050
61 + 31583989 = 31584050
67 + 31583983 = 31584050
79 + 31583971 = 31584050
109 + 31583941 = 31584050
139 + 31583911 = 31584050
193 + 31583857 = 31584050

Showing the first eight; more decompositions exist.
