Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938828, here are decompositions:

67 + 938761 = 938828
151 + 938677 = 938828
211 + 938617 = 938828
337 + 938491 = 938828
487 + 938341 = 938828
571 + 938257 = 938828
577 + 938251 = 938828
739 + 938089 = 938828

Showing the first eight; more decompositions exist.
