Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108018, here are decompositions:

5 + 108013 = 108018
7 + 108011 = 108018
11 + 108007 = 108018
19 + 107999 = 108018
37 + 107981 = 108018
47 + 107971 = 108018
67 + 107951 = 108018
137 + 107881 = 108018

Showing the first eight; more decompositions exist.
