Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20182, here are decompositions:

5 + 20177 = 20182
53 + 20129 = 20182
59 + 20123 = 20182
131 + 20051 = 20182
191 + 19991 = 20182
233 + 19949 = 20182
263 + 19919 = 20182
269 + 19913 = 20182

Showing the first eight; more decompositions exist.
