Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938212, here are decompositions:

5 + 938207 = 938212
29 + 938183 = 938212
83 + 938129 = 938212
113 + 938099 = 938212
179 + 938033 = 938212
263 + 937949 = 938212
269 + 937943 = 938212
293 + 937919 = 938212

Showing the first eight; more decompositions exist.
