Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68018, here are decompositions:

31 + 67987 = 68018
61 + 67957 = 68018
79 + 67939 = 68018
127 + 67891 = 68018
151 + 67867 = 68018
199 + 67819 = 68018
211 + 67807 = 68018
229 + 67789 = 68018

Showing the first eight; more decompositions exist.
