Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20396, here are decompositions:

3 + 20393 = 20396
7 + 20389 = 20396
37 + 20359 = 20396
43 + 20353 = 20396
73 + 20323 = 20396
109 + 20287 = 20396
127 + 20269 = 20396
163 + 20233 = 20396

Showing the first eight; more decompositions exist.
