Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938200, here are decompositions:

17 + 938183 = 938200
71 + 938129 = 938200
83 + 938117 = 938200
101 + 938099 = 938200
149 + 938051 = 938200
167 + 938033 = 938200
173 + 938027 = 938200
251 + 937949 = 938200

Showing the first eight; more decompositions exist.
