Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938198, here are decompositions:

109 + 938089 = 938198
127 + 938071 = 938198
139 + 938059 = 938198
181 + 938017 = 938198
229 + 937969 = 938198
271 + 937927 = 938198
307 + 937891 = 938198
379 + 937819 = 938198

Showing the first eight; more decompositions exist.
