Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584152, here are decompositions:

13 + 31584139 = 31584152
109 + 31584043 = 31584152
163 + 31583989 = 31584152
181 + 31583971 = 31584152
211 + 31583941 = 31584152
241 + 31583911 = 31584152
349 + 31583803 = 31584152
373 + 31583779 = 31584152

Showing the first eight; more decompositions exist.
