Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126966, here are decompositions:

5 + 126961 = 126966
17 + 126949 = 126966
23 + 126943 = 126966
43 + 126923 = 126966
53 + 126913 = 126966
107 + 126859 = 126966
109 + 126857 = 126966
127 + 126839 = 126966

Showing the first eight; more decompositions exist.
