Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47808, here are decompositions:

11 + 47797 = 47808
17 + 47791 = 47808
29 + 47779 = 47808
31 + 47777 = 47808
67 + 47741 = 47808
71 + 47737 = 47808
97 + 47711 = 47808
107 + 47701 = 47808

Showing the first eight; more decompositions exist.
