Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026920, here are decompositions:

3 + 1026917 = 1026920
7 + 1026913 = 1026920
61 + 1026859 = 1026920
67 + 1026853 = 1026920
73 + 1026847 = 1026920
109 + 1026811 = 1026920
163 + 1026757 = 1026920
211 + 1026709 = 1026920

Showing the first eight; more decompositions exist.
