Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028290, here are decompositions:

17 + 1028273 = 1028290
47 + 1028243 = 1028290
59 + 1028231 = 1028290
83 + 1028207 = 1028290
89 + 1028201 = 1028290
101 + 1028189 = 1028290
149 + 1028141 = 1028290
173 + 1028117 = 1028290

Showing the first eight; more decompositions exist.
