Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584162, here are decompositions:

19 + 31584143 = 31584162
23 + 31584139 = 31584162
61 + 31584101 = 31584162
163 + 31583999 = 31584162
173 + 31583989 = 31584162
179 + 31583983 = 31584162
191 + 31583971 = 31584162
241 + 31583921 = 31584162

Showing the first eight; more decompositions exist.
