Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523880, here are decompositions:

3 + 523877 = 523880
13 + 523867 = 523880
79 + 523801 = 523880
103 + 523777 = 523880
109 + 523771 = 523880
139 + 523741 = 523880
151 + 523729 = 523880
163 + 523717 = 523880

Showing the first eight; more decompositions exist.
