Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8270, here are decompositions:

7 + 8263 = 8270
37 + 8233 = 8270
61 + 8209 = 8270
79 + 8191 = 8270
103 + 8167 = 8270
109 + 8161 = 8270
181 + 8089 = 8270
211 + 8059 = 8270

Showing the first eight; more decompositions exist.
