Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11566, here are decompositions:

17 + 11549 = 11566
47 + 11519 = 11566
83 + 11483 = 11566
167 + 11399 = 11566
173 + 11393 = 11566
197 + 11369 = 11566
293 + 11273 = 11566
353 + 11213 = 11566

Showing the first eight; more decompositions exist.
