Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20354, here are decompositions:

7 + 20347 = 20354
13 + 20341 = 20354
31 + 20323 = 20354
67 + 20287 = 20354
181 + 20173 = 20354
193 + 20161 = 20354
211 + 20143 = 20354
241 + 20113 = 20354

Showing the first eight; more decompositions exist.
