Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026780, here are decompositions:

19 + 1026761 = 1026780
23 + 1026757 = 1026780
47 + 1026733 = 1026780
71 + 1026709 = 1026780
101 + 1026679 = 1026780
103 + 1026677 = 1026780
107 + 1026673 = 1026780
113 + 1026667 = 1026780

Showing the first eight; more decompositions exist.
