Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20342, here are decompositions:

19 + 20323 = 20342
73 + 20269 = 20342
109 + 20233 = 20342
181 + 20161 = 20342
193 + 20149 = 20342
199 + 20143 = 20342
229 + 20113 = 20342
241 + 20101 = 20342

Showing the first eight; more decompositions exist.
