Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938180, here are decompositions:

73 + 938107 = 938180
97 + 938083 = 938180
109 + 938071 = 938180
127 + 938053 = 938180
157 + 938023 = 938180
163 + 938017 = 938180
211 + 937969 = 938180
277 + 937903 = 938180

Showing the first eight; more decompositions exist.
