Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121896, here are decompositions:

7 + 121889 = 121896
13 + 121883 = 121896
29 + 121867 = 121896
43 + 121853 = 121896
53 + 121843 = 121896
107 + 121789 = 121896
109 + 121787 = 121896
199 + 121697 = 121896

Showing the first eight; more decompositions exist.
