Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017828, here are decompositions:

11 + 1017817 = 1017828
29 + 1017799 = 1017828
41 + 1017787 = 1017828
47 + 1017781 = 1017828
79 + 1017749 = 1017828
107 + 1017721 = 1017828
109 + 1017719 = 1017828
179 + 1017649 = 1017828

Showing the first eight; more decompositions exist.
