Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71898, here are decompositions:

11 + 71887 = 71898
17 + 71881 = 71898
19 + 71879 = 71898
31 + 71867 = 71898
37 + 71861 = 71898
61 + 71837 = 71898
89 + 71809 = 71898
109 + 71789 = 71898

Showing the first eight; more decompositions exist.
