Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938316, here are decompositions:

7 + 938309 = 938316
23 + 938293 = 938316
37 + 938279 = 938316
53 + 938263 = 938316
59 + 938257 = 938316
73 + 938243 = 938316
83 + 938233 = 938316
97 + 938219 = 938316

Showing the first eight; more decompositions exist.
