Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20934, here are decompositions:

5 + 20929 = 20934
13 + 20921 = 20934
31 + 20903 = 20934
37 + 20897 = 20934
47 + 20887 = 20934
61 + 20873 = 20934
127 + 20807 = 20934
163 + 20771 = 20934

Showing the first eight; more decompositions exist.
