Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938428, here are decompositions:

41 + 938387 = 938428
59 + 938369 = 938428
149 + 938279 = 938428
311 + 938117 = 938428
401 + 938027 = 938428
479 + 937949 = 938428
509 + 937919 = 938428
587 + 937841 = 938428

Showing the first eight; more decompositions exist.
