Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105406, here are decompositions:

5 + 105401 = 105406
17 + 105389 = 105406
47 + 105359 = 105406
83 + 105323 = 105406
137 + 105269 = 105406
167 + 105239 = 105406
179 + 105227 = 105406
233 + 105173 = 105406

Showing the first eight; more decompositions exist.
