Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40018, here are decompositions:

5 + 40013 = 40018
29 + 39989 = 40018
47 + 39971 = 40018
89 + 39929 = 40018
131 + 39887 = 40018
149 + 39869 = 40018
179 + 39839 = 40018
191 + 39827 = 40018

Showing the first eight; more decompositions exist.
