Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105876, here are decompositions:

5 + 105871 = 105876
13 + 105863 = 105876
47 + 105829 = 105876
59 + 105817 = 105876
107 + 105769 = 105876
109 + 105767 = 105876
149 + 105727 = 105876
193 + 105683 = 105876

Showing the first eight; more decompositions exist.
