Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105916, here are decompositions:

3 + 105913 = 105916
17 + 105899 = 105916
53 + 105863 = 105916
149 + 105767 = 105916
233 + 105683 = 105916
263 + 105653 = 105916
353 + 105563 = 105916
359 + 105557 = 105916

Showing the first eight; more decompositions exist.
