Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11528, here are decompositions:

31 + 11497 = 11528
37 + 11491 = 11528
61 + 11467 = 11528
199 + 11329 = 11528
211 + 11317 = 11528
229 + 11299 = 11528
241 + 11287 = 11528
271 + 11257 = 11528

Showing the first eight; more decompositions exist.
