Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523878, here are decompositions:

11 + 523867 = 523878
31 + 523847 = 523878
101 + 523777 = 523878
107 + 523771 = 523878
137 + 523741 = 523878
149 + 523729 = 523878
197 + 523681 = 523878
211 + 523667 = 523878

Showing the first eight; more decompositions exist.
