Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026556, here are decompositions:

107 + 1026449 = 1026556
149 + 1026407 = 1026556
173 + 1026383 = 1026556
197 + 1026359 = 1026556
257 + 1026299 = 1026556
263 + 1026293 = 1026556
359 + 1026197 = 1026556
389 + 1026167 = 1026556

Showing the first eight; more decompositions exist.
