Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103920, here are decompositions:

7 + 103913 = 103920
17 + 103903 = 103920
31 + 103889 = 103920
53 + 103867 = 103920
79 + 103841 = 103920
83 + 103837 = 103920
107 + 103813 = 103920
109 + 103811 = 103920

Showing the first eight; more decompositions exist.
