Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8306, here are decompositions:

13 + 8293 = 8306
19 + 8287 = 8306
37 + 8269 = 8306
43 + 8263 = 8306
73 + 8233 = 8306
97 + 8209 = 8306
127 + 8179 = 8306
139 + 8167 = 8306

Showing the first eight; more decompositions exist.
