Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40036, here are decompositions:

5 + 40031 = 40036
23 + 40013 = 40036
47 + 39989 = 40036
53 + 39983 = 40036
83 + 39953 = 40036
107 + 39929 = 40036
149 + 39887 = 40036
167 + 39869 = 40036

Showing the first eight; more decompositions exist.
