Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20426, here are decompositions:

19 + 20407 = 20426
37 + 20389 = 20426
67 + 20359 = 20426
73 + 20353 = 20426
79 + 20347 = 20426
103 + 20323 = 20426
139 + 20287 = 20426
157 + 20269 = 20426

Showing the first eight; more decompositions exist.
