Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026860, here are decompositions:

7 + 1026853 = 1026860
13 + 1026847 = 1026860
31 + 1026829 = 1026860
61 + 1026799 = 1026860
103 + 1026757 = 1026860
127 + 1026733 = 1026860
151 + 1026709 = 1026860
181 + 1026679 = 1026860

Showing the first eight; more decompositions exist.
