Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105166, here are decompositions:

23 + 105143 = 105166
29 + 105137 = 105166
59 + 105107 = 105166
167 + 104999 = 105166
179 + 104987 = 105166
233 + 104933 = 105166
317 + 104849 = 105166
443 + 104723 = 105166

Showing the first eight; more decompositions exist.
