Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40006, here are decompositions:

17 + 39989 = 40006
23 + 39983 = 40006
53 + 39953 = 40006
137 + 39869 = 40006
149 + 39857 = 40006
167 + 39839 = 40006
179 + 39827 = 40006
227 + 39779 = 40006

Showing the first eight; more decompositions exist.
