Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940428, here are decompositions:

7 + 940421 = 940428
29 + 940399 = 940428
59 + 940369 = 940428
67 + 940361 = 940428
79 + 940349 = 940428
101 + 940327 = 940428
109 + 940319 = 940428
127 + 940301 = 940428

Showing the first eight; more decompositions exist.
