Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11940, here are decompositions:

7 + 11933 = 11940
13 + 11927 = 11940
17 + 11923 = 11940
31 + 11909 = 11940
37 + 11903 = 11940
43 + 11897 = 11940
53 + 11887 = 11940
73 + 11867 = 11940

Showing the first eight; more decompositions exist.
