Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20338, here are decompositions:

5 + 20333 = 20338
11 + 20327 = 20338
41 + 20297 = 20338
89 + 20249 = 20338
107 + 20231 = 20338
137 + 20201 = 20338
191 + 20147 = 20338
317 + 20021 = 20338

Showing the first eight; more decompositions exist.
