Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584146, here are decompositions:

3 + 31584143 = 31584146
7 + 31584139 = 31584146
79 + 31584067 = 31584146
103 + 31584043 = 31584146
127 + 31584019 = 31584146
157 + 31583989 = 31584146
163 + 31583983 = 31584146
283 + 31583863 = 31584146

Showing the first eight; more decompositions exist.
