Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584182, here are decompositions:

43 + 31584139 = 31584182
139 + 31584043 = 31584182
163 + 31584019 = 31584182
193 + 31583989 = 31584182
199 + 31583983 = 31584182
211 + 31583971 = 31584182
241 + 31583941 = 31584182
271 + 31583911 = 31584182

Showing the first eight; more decompositions exist.
