Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938486, here are decompositions:

127 + 938359 = 938486
139 + 938347 = 938486
163 + 938323 = 938486
193 + 938293 = 938486
223 + 938263 = 938486
229 + 938257 = 938486
379 + 938107 = 938486
397 + 938089 = 938486

Showing the first eight; more decompositions exist.
