Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20200, here are decompositions:

17 + 20183 = 20200
23 + 20177 = 20200
53 + 20147 = 20200
71 + 20129 = 20200
83 + 20117 = 20200
137 + 20063 = 20200
149 + 20051 = 20200
179 + 20021 = 20200

Showing the first eight; more decompositions exist.
