Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121938, here are decompositions:

7 + 121931 = 121938
17 + 121921 = 121938
29 + 121909 = 121938
71 + 121867 = 121938
149 + 121789 = 121938
151 + 121787 = 121938
211 + 121727 = 121938
227 + 121711 = 121938

Showing the first eight; more decompositions exist.
