Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536878, here are decompositions:

11 + 536867 = 536878
29 + 536849 = 536878
101 + 536777 = 536878
107 + 536771 = 536878
149 + 536729 = 536878
179 + 536699 = 536878
191 + 536687 = 536878
227 + 536651 = 536878

Showing the first eight; more decompositions exist.
