Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105418, here are decompositions:

11 + 105407 = 105418
17 + 105401 = 105418
29 + 105389 = 105418
59 + 105359 = 105418
149 + 105269 = 105418
167 + 105251 = 105418
179 + 105239 = 105418
191 + 105227 = 105418

Showing the first eight; more decompositions exist.
