Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108218, here are decompositions:

7 + 108211 = 108218
31 + 108187 = 108218
79 + 108139 = 108218
109 + 108109 = 108218
139 + 108079 = 108218
157 + 108061 = 108218
181 + 108037 = 108218
211 + 108007 = 108218

Showing the first eight; more decompositions exist.
