Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10018, here are decompositions:

11 + 10007 = 10018
89 + 9929 = 10018
131 + 9887 = 10018
167 + 9851 = 10018
179 + 9839 = 10018
227 + 9791 = 10018
251 + 9767 = 10018
269 + 9749 = 10018

Showing the first eight; more decompositions exist.
