Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11700, here are decompositions:

11 + 11689 = 11700
19 + 11681 = 11700
23 + 11677 = 11700
43 + 11657 = 11700
67 + 11633 = 11700
79 + 11621 = 11700
83 + 11617 = 11700
103 + 11597 = 11700

Showing the first eight; more decompositions exist.
