Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11756, here are decompositions:

13 + 11743 = 11756
37 + 11719 = 11756
67 + 11689 = 11756
79 + 11677 = 11756
139 + 11617 = 11756
163 + 11593 = 11756
229 + 11527 = 11756
313 + 11443 = 11756

Showing the first eight; more decompositions exist.
