Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026690, here are decompositions:

11 + 1026679 = 1026690
13 + 1026677 = 1026690
17 + 1026673 = 1026690
23 + 1026667 = 1026690
29 + 1026661 = 1026690
97 + 1026593 = 1026690
103 + 1026587 = 1026690
107 + 1026583 = 1026690

Showing the first eight; more decompositions exist.
