Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20300, here are decompositions:

3 + 20297 = 20300
13 + 20287 = 20300
31 + 20269 = 20300
67 + 20233 = 20300
127 + 20173 = 20300
139 + 20161 = 20300
151 + 20149 = 20300
157 + 20143 = 20300

Showing the first eight; more decompositions exist.
