Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938438, here are decompositions:

79 + 938359 = 938438
97 + 938341 = 938438
181 + 938257 = 938438
331 + 938107 = 938438
349 + 938089 = 938438
367 + 938071 = 938438
379 + 938059 = 938438
421 + 938017 = 938438

Showing the first eight; more decompositions exist.
