Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105968, here are decompositions:

61 + 105907 = 105968
97 + 105871 = 105968
139 + 105829 = 105968
151 + 105817 = 105968
199 + 105769 = 105968
241 + 105727 = 105968
277 + 105691 = 105968
349 + 105619 = 105968

Showing the first eight; more decompositions exist.
