Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17940, here are decompositions:

11 + 17929 = 17940
17 + 17923 = 17940
19 + 17921 = 17940
29 + 17911 = 17940
31 + 17909 = 17940
37 + 17903 = 17940
59 + 17881 = 17940
89 + 17851 = 17940

Showing the first eight; more decompositions exist.
