Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026406, here are decompositions:

5 + 1026401 = 1026406
23 + 1026383 = 1026406
47 + 1026359 = 1026406
107 + 1026299 = 1026406
113 + 1026293 = 1026406
149 + 1026257 = 1026406
179 + 1026227 = 1026406
239 + 1026167 = 1026406

Showing the first eight; more decompositions exist.
