Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80306, here are decompositions:

19 + 80287 = 80306
43 + 80263 = 80306
67 + 80239 = 80306
73 + 80233 = 80306
97 + 80209 = 80306
139 + 80167 = 80306
157 + 80149 = 80306
199 + 80107 = 80306

Showing the first eight; more decompositions exist.
