Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026818, here are decompositions:

7 + 1026811 = 1026818
19 + 1026799 = 1026818
61 + 1026757 = 1026818
109 + 1026709 = 1026818
139 + 1026679 = 1026818
151 + 1026667 = 1026818
157 + 1026661 = 1026818
241 + 1026577 = 1026818

Showing the first eight; more decompositions exist.
