Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938398, here are decompositions:

5 + 938393 = 938398
11 + 938387 = 938398
29 + 938369 = 938398
47 + 938351 = 938398
89 + 938309 = 938398
179 + 938219 = 938398
191 + 938207 = 938398
269 + 938129 = 938398

Showing the first eight; more decompositions exist.
