Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82210, here are decompositions:

3 + 82207 = 82210
17 + 82193 = 82210
47 + 82163 = 82210
71 + 82139 = 82210
137 + 82073 = 82210
173 + 82037 = 82210
179 + 82031 = 82210
197 + 82013 = 82210

Showing the first eight; more decompositions exist.
