Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943428, here are decompositions:

7 + 943421 = 943428
19 + 943409 = 943428
41 + 943387 = 943428
61 + 943367 = 943428
71 + 943357 = 943428
107 + 943321 = 943428
127 + 943301 = 943428
139 + 943289 = 943428

Showing the first eight; more decompositions exist.
