Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20424, here are decompositions:

13 + 20411 = 20424
17 + 20407 = 20424
31 + 20393 = 20424
67 + 20357 = 20424
71 + 20353 = 20424
83 + 20341 = 20424
97 + 20327 = 20424
101 + 20323 = 20424

Showing the first eight; more decompositions exist.
