Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20326, here are decompositions:

3 + 20323 = 20326
29 + 20297 = 20326
107 + 20219 = 20326
149 + 20177 = 20326
179 + 20147 = 20326
197 + 20129 = 20326
263 + 20063 = 20326
347 + 19979 = 20326

Showing the first eight; more decompositions exist.
