Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21336, here are decompositions:

13 + 21323 = 21336
17 + 21319 = 21336
19 + 21317 = 21336
23 + 21313 = 21336
53 + 21283 = 21336
59 + 21277 = 21336
67 + 21269 = 21336
89 + 21247 = 21336

Showing the first eight; more decompositions exist.
