Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11928, here are decompositions:

5 + 11923 = 11928
19 + 11909 = 11928
31 + 11897 = 11928
41 + 11887 = 11928
61 + 11867 = 11928
89 + 11839 = 11928
97 + 11831 = 11928
101 + 11827 = 11928

Showing the first eight; more decompositions exist.
