Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026628, here are decompositions:

41 + 1026587 = 1026628
47 + 1026581 = 1026628
107 + 1026521 = 1026628
149 + 1026479 = 1026628
179 + 1026449 = 1026628
227 + 1026401 = 1026628
257 + 1026371 = 1026628
269 + 1026359 = 1026628

Showing the first eight; more decompositions exist.
