Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584004, here are decompositions:

5 + 31583999 = 31584004
83 + 31583921 = 31584004
107 + 31583897 = 31584004
167 + 31583837 = 31584004
173 + 31583831 = 31584004
227 + 31583777 = 31584004
233 + 31583771 = 31584004
251 + 31583753 = 31584004

Showing the first eight; more decompositions exist.
