Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028826, here are decompositions:

17 + 1028809 = 1028826
23 + 1028803 = 1028826
53 + 1028773 = 1028826
79 + 1028747 = 1028826
89 + 1028737 = 1028826
157 + 1028669 = 1028826
163 + 1028663 = 1028826
179 + 1028647 = 1028826

Showing the first eight; more decompositions exist.
