Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47898, here are decompositions:

17 + 47881 = 47898
29 + 47869 = 47898
41 + 47857 = 47898
61 + 47837 = 47898
79 + 47819 = 47898
89 + 47809 = 47898
101 + 47797 = 47898
107 + 47791 = 47898

Showing the first eight; more decompositions exist.
