Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938188, here are decompositions:

5 + 938183 = 938188
59 + 938129 = 938188
71 + 938117 = 938188
89 + 938099 = 938188
131 + 938057 = 938188
137 + 938051 = 938188
197 + 937991 = 938188
239 + 937949 = 938188

Showing the first eight; more decompositions exist.
