Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026866, here are decompositions:

7 + 1026859 = 1026866
13 + 1026853 = 1026866
19 + 1026847 = 1026866
37 + 1026829 = 1026866
67 + 1026799 = 1026866
109 + 1026757 = 1026866
157 + 1026709 = 1026866
193 + 1026673 = 1026866

Showing the first eight; more decompositions exist.
