Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584010, here are decompositions:

11 + 31583999 = 31584010
89 + 31583921 = 31584010
113 + 31583897 = 31584010
173 + 31583837 = 31584010
179 + 31583831 = 31584010
191 + 31583819 = 31584010
233 + 31583777 = 31584010
239 + 31583771 = 31584010

Showing the first eight; more decompositions exist.
