Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105946, here are decompositions:

3 + 105943 = 105946
17 + 105929 = 105946
47 + 105899 = 105946
83 + 105863 = 105946
179 + 105767 = 105946
263 + 105683 = 105946
293 + 105653 = 105946
383 + 105563 = 105946

Showing the first eight; more decompositions exist.
