Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11516, here are decompositions:

13 + 11503 = 11516
19 + 11497 = 11516
73 + 11443 = 11516
79 + 11437 = 11516
163 + 11353 = 11516
199 + 11317 = 11516
229 + 11287 = 11516
277 + 11239 = 11516

Showing the first eight; more decompositions exist.
