Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105978, here are decompositions:

7 + 105971 = 105978
11 + 105967 = 105978
71 + 105907 = 105978
79 + 105899 = 105978
107 + 105871 = 105978
149 + 105829 = 105978
211 + 105767 = 105978
227 + 105751 = 105978

Showing the first eight; more decompositions exist.
