Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608004, here are decompositions:

83 + 31607921 = 31608004
101 + 31607903 = 31608004
107 + 31607897 = 31608004
137 + 31607867 = 31608004
173 + 31607831 = 31608004
257 + 31607747 = 31608004
317 + 31607687 = 31608004
557 + 31607447 = 31608004

Showing the first eight; more decompositions exist.
