Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20436, here are decompositions:

5 + 20431 = 20436
29 + 20407 = 20436
37 + 20399 = 20436
43 + 20393 = 20436
47 + 20389 = 20436
67 + 20369 = 20436
79 + 20357 = 20436
83 + 20353 = 20436

Showing the first eight; more decompositions exist.
