Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030428, here are decompositions:

11 + 1030417 = 1030428
17 + 1030411 = 1030428
59 + 1030369 = 1030428
67 + 1030361 = 1030428
71 + 1030357 = 1030428
79 + 1030349 = 1030428
131 + 1030297 = 1030428
137 + 1030291 = 1030428

Showing the first eight; more decompositions exist.
