Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13920, here are decompositions:

7 + 13913 = 13920
13 + 13907 = 13920
17 + 13903 = 13920
19 + 13901 = 13920
37 + 13883 = 13920
41 + 13879 = 13920
43 + 13877 = 13920
47 + 13873 = 13920

Showing the first eight; more decompositions exist.
