Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584196, here are decompositions:

3 + 31584193 = 31584196
5 + 31584191 = 31584196
23 + 31584173 = 31584196
53 + 31584143 = 31584196
197 + 31583999 = 31584196
359 + 31583837 = 31584196
419 + 31583777 = 31584196
443 + 31583753 = 31584196

Showing the first eight; more decompositions exist.
