Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938240, here are decompositions:

7 + 938233 = 938240
151 + 938089 = 938240
157 + 938083 = 938240
181 + 938059 = 938240
223 + 938017 = 938240
271 + 937969 = 938240
313 + 937927 = 938240
337 + 937903 = 938240

Showing the first eight; more decompositions exist.
