Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17898, here are decompositions:

7 + 17891 = 17898
17 + 17881 = 17898
47 + 17851 = 17898
59 + 17839 = 17898
61 + 17837 = 17898
71 + 17827 = 17898
107 + 17791 = 17898
109 + 17789 = 17898

Showing the first eight; more decompositions exist.
