Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009428, here are decompositions:

11 + 1009417 = 1009428
29 + 1009399 = 1009428
41 + 1009387 = 1009428
59 + 1009369 = 1009428
67 + 1009361 = 1009428
71 + 1009357 = 1009428
107 + 1009321 = 1009428
109 + 1009319 = 1009428

Showing the first eight; more decompositions exist.
