Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105160, here are decompositions:

17 + 105143 = 105160
23 + 105137 = 105160
53 + 105107 = 105160
89 + 105071 = 105160
137 + 105023 = 105160
173 + 104987 = 105160
227 + 104933 = 105160
269 + 104891 = 105160

Showing the first eight; more decompositions exist.
