Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938170, here are decompositions:

41 + 938129 = 938170
53 + 938117 = 938170
71 + 938099 = 938170
113 + 938057 = 938170
137 + 938033 = 938170
179 + 937991 = 938170
227 + 937943 = 938170
251 + 937919 = 938170

Showing the first eight; more decompositions exist.
