Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584132, here are decompositions:

31 + 31584101 = 31584132
89 + 31584043 = 31584132
113 + 31584019 = 31584132
149 + 31583983 = 31584132
191 + 31583941 = 31584132
211 + 31583921 = 31584132
269 + 31583863 = 31584132
313 + 31583819 = 31584132

Showing the first eight; more decompositions exist.
