Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8210, here are decompositions:

19 + 8191 = 8210
31 + 8179 = 8210
43 + 8167 = 8210
109 + 8101 = 8210
151 + 8059 = 8210
157 + 8053 = 8210
193 + 8017 = 8210
199 + 8011 = 8210

Showing the first eight; more decompositions exist.
