Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028210, here are decompositions:

3 + 1028207 = 1028210
19 + 1028191 = 1028210
61 + 1028149 = 1028210
97 + 1028113 = 1028210
103 + 1028107 = 1028210
109 + 1028101 = 1028210
163 + 1028047 = 1028210
181 + 1028029 = 1028210

Showing the first eight; more decompositions exist.
