Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20188, here are decompositions:

5 + 20183 = 20188
11 + 20177 = 20188
41 + 20147 = 20188
59 + 20129 = 20188
71 + 20117 = 20188
137 + 20051 = 20188
167 + 20021 = 20188
191 + 19997 = 20188

Showing the first eight; more decompositions exist.
