Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11728, here are decompositions:

11 + 11717 = 11728
29 + 11699 = 11728
47 + 11681 = 11728
71 + 11657 = 11728
107 + 11621 = 11728
131 + 11597 = 11728
149 + 11579 = 11728
179 + 11549 = 11728

Showing the first eight; more decompositions exist.
