Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20914, here are decompositions:

11 + 20903 = 20914
17 + 20897 = 20914
41 + 20873 = 20914
107 + 20807 = 20914
167 + 20747 = 20914
197 + 20717 = 20914
233 + 20681 = 20914
251 + 20663 = 20914

Showing the first eight; more decompositions exist.
