Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061878, here are decompositions:

11 + 1061867 = 1061878
29 + 1061849 = 1061878
47 + 1061831 = 1061878
71 + 1061807 = 1061878
107 + 1061771 = 1061878
149 + 1061729 = 1061878
179 + 1061699 = 1061878
227 + 1061651 = 1061878

Showing the first eight; more decompositions exist.
