Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026666, here are decompositions:

5 + 1026661 = 1026666
73 + 1026593 = 1026666
79 + 1026587 = 1026666
83 + 1026583 = 1026666
89 + 1026577 = 1026666
103 + 1026563 = 1026666
227 + 1026439 = 1026666
239 + 1026427 = 1026666

Showing the first eight; more decompositions exist.
