Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20358, here are decompositions:

5 + 20353 = 20358
11 + 20347 = 20358
17 + 20341 = 20358
31 + 20327 = 20358
61 + 20297 = 20358
71 + 20287 = 20358
89 + 20269 = 20358
97 + 20261 = 20358

Showing the first eight; more decompositions exist.
