Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17928, here are decompositions:

5 + 17923 = 17928
7 + 17921 = 17928
17 + 17911 = 17928
19 + 17909 = 17928
37 + 17891 = 17928
47 + 17881 = 17928
89 + 17839 = 17928
101 + 17827 = 17928

Showing the first eight; more decompositions exist.
