Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938146, here are decompositions:

17 + 938129 = 938146
29 + 938117 = 938146
47 + 938099 = 938146
89 + 938057 = 938146
113 + 938033 = 938146
197 + 937949 = 938146
227 + 937919 = 938146
263 + 937883 = 938146

Showing the first eight; more decompositions exist.
