Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10188, here are decompositions:

7 + 10181 = 10188
11 + 10177 = 10188
19 + 10169 = 10188
29 + 10159 = 10188
37 + 10151 = 10188
47 + 10141 = 10188
89 + 10099 = 10188
97 + 10091 = 10188

Showing the first eight; more decompositions exist.
