Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10356, here are decompositions:

13 + 10343 = 10356
19 + 10337 = 10356
23 + 10333 = 10356
43 + 10313 = 10356
53 + 10303 = 10356
67 + 10289 = 10356
83 + 10273 = 10356
89 + 10267 = 10356

Showing the first eight; more decompositions exist.
