Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938402, here are decompositions:

43 + 938359 = 938402
61 + 938341 = 938402
79 + 938323 = 938402
109 + 938293 = 938402
139 + 938263 = 938402
151 + 938251 = 938402
313 + 938089 = 938402
331 + 938071 = 938402

Showing the first eight; more decompositions exist.
