Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938238, here are decompositions:

5 + 938233 = 938238
19 + 938219 = 938238
31 + 938207 = 938238
109 + 938129 = 938238
131 + 938107 = 938238
139 + 938099 = 938238
149 + 938089 = 938238
167 + 938071 = 938238

Showing the first eight; more decompositions exist.
