Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105942, here are decompositions:

13 + 105929 = 105942
29 + 105913 = 105942
43 + 105899 = 105942
59 + 105883 = 105942
71 + 105871 = 105942
79 + 105863 = 105942
113 + 105829 = 105942
173 + 105769 = 105942

Showing the first eight; more decompositions exist.
