Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938224, here are decompositions:

5 + 938219 = 938224
17 + 938207 = 938224
41 + 938183 = 938224
107 + 938117 = 938224
167 + 938057 = 938224
173 + 938051 = 938224
191 + 938033 = 938224
197 + 938027 = 938224

Showing the first eight; more decompositions exist.
