Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20344, here are decompositions:

3 + 20341 = 20344
11 + 20333 = 20344
17 + 20327 = 20344
47 + 20297 = 20344
83 + 20261 = 20344
113 + 20231 = 20344
167 + 20177 = 20344
197 + 20147 = 20344

Showing the first eight; more decompositions exist.
