Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121884, here are decompositions:

17 + 121867 = 121884
31 + 121853 = 121884
41 + 121843 = 121884
97 + 121787 = 121884
157 + 121727 = 121884
163 + 121721 = 121884
173 + 121711 = 121884
197 + 121687 = 121884

Showing the first eight; more decompositions exist.
