Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20216, here are decompositions:

43 + 20173 = 20216
67 + 20149 = 20216
73 + 20143 = 20216
103 + 20113 = 20216
109 + 20107 = 20216
127 + 20089 = 20216
193 + 20023 = 20216
223 + 19993 = 20216

Showing the first eight; more decompositions exist.
