Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938156, here are decompositions:

67 + 938089 = 938156
73 + 938083 = 938156
97 + 938059 = 938156
103 + 938053 = 938156
139 + 938017 = 938156
229 + 937927 = 938156
337 + 937819 = 938156
367 + 937789 = 938156

Showing the first eight; more decompositions exist.
