Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584204, here are decompositions:

7 + 31584197 = 31584204
11 + 31584193 = 31584204
13 + 31584191 = 31584204
31 + 31584173 = 31584204
61 + 31584143 = 31584204
103 + 31584101 = 31584204
137 + 31584067 = 31584204
233 + 31583971 = 31584204

Showing the first eight; more decompositions exist.
