Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11436, here are decompositions:

13 + 11423 = 11436
37 + 11399 = 11436
43 + 11393 = 11436
53 + 11383 = 11436
67 + 11369 = 11436
83 + 11353 = 11436
107 + 11329 = 11436
137 + 11299 = 11436

Showing the first eight; more decompositions exist.
