Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82218, here are decompositions:

11 + 82207 = 82218
29 + 82189 = 82218
47 + 82171 = 82218
79 + 82139 = 82218
89 + 82129 = 82218
151 + 82067 = 82218
167 + 82051 = 82218
179 + 82039 = 82218

Showing the first eight; more decompositions exist.
