Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938306, here are decompositions:

13 + 938293 = 938306
43 + 938263 = 938306
73 + 938233 = 938306
199 + 938107 = 938306
223 + 938083 = 938306
283 + 938023 = 938306
337 + 937969 = 938306
379 + 937927 = 938306

Showing the first eight; more decompositions exist.
