Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028906, here are decompositions:

3 + 1028903 = 1028906
13 + 1028893 = 1028906
97 + 1028809 = 1028906
103 + 1028803 = 1028906
157 + 1028749 = 1028906
223 + 1028683 = 1028906
337 + 1028569 = 1028906
349 + 1028557 = 1028906

Showing the first eight; more decompositions exist.
