Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20310, here are decompositions:

13 + 20297 = 20310
23 + 20287 = 20310
41 + 20269 = 20310
61 + 20249 = 20310
79 + 20231 = 20310
109 + 20201 = 20310
127 + 20183 = 20310
137 + 20173 = 20310

Showing the first eight; more decompositions exist.
