Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109920, here are decompositions:

7 + 109913 = 109920
17 + 109903 = 109920
23 + 109897 = 109920
29 + 109891 = 109920
37 + 109883 = 109920
47 + 109873 = 109920
61 + 109859 = 109920
71 + 109849 = 109920

Showing the first eight; more decompositions exist.
