Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11920, here are decompositions:

11 + 11909 = 11920
17 + 11903 = 11920
23 + 11897 = 11920
53 + 11867 = 11920
89 + 11831 = 11920
107 + 11813 = 11920
113 + 11807 = 11920
131 + 11789 = 11920

Showing the first eight; more decompositions exist.
