Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523808, here are decompositions:

7 + 523801 = 523808
31 + 523777 = 523808
37 + 523771 = 523808
67 + 523741 = 523808
79 + 523729 = 523808
127 + 523681 = 523808
139 + 523669 = 523808
151 + 523657 = 523808

Showing the first eight; more decompositions exist.
