Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20086, here are decompositions:

23 + 20063 = 20086
89 + 19997 = 20086
107 + 19979 = 20086
113 + 19973 = 20086
137 + 19949 = 20086
149 + 19937 = 20086
167 + 19919 = 20086
173 + 19913 = 20086

Showing the first eight; more decompositions exist.
