Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938148, here are decompositions:

19 + 938129 = 938148
31 + 938117 = 938148
41 + 938107 = 938148
59 + 938089 = 938148
89 + 938059 = 938148
97 + 938051 = 938148
131 + 938017 = 938148
157 + 937991 = 938148

Showing the first eight; more decompositions exist.
