Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11718, here are decompositions:

17 + 11701 = 11718
19 + 11699 = 11718
29 + 11689 = 11718
37 + 11681 = 11718
41 + 11677 = 11718
61 + 11657 = 11718
97 + 11621 = 11718
101 + 11617 = 11718

Showing the first eight; more decompositions exist.
