Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40168, here are decompositions:

5 + 40163 = 40168
17 + 40151 = 40168
41 + 40127 = 40168
131 + 40037 = 40168
137 + 40031 = 40168
179 + 39989 = 40168
197 + 39971 = 40168
239 + 39929 = 40168

Showing the first eight; more decompositions exist.
