Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103188, here are decompositions:

5 + 103183 = 103188
11 + 103177 = 103188
17 + 103171 = 103188
47 + 103141 = 103188
89 + 103099 = 103188
97 + 103091 = 103188
101 + 103087 = 103188
109 + 103079 = 103188

Showing the first eight; more decompositions exist.
