Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105950, here are decompositions:

7 + 105943 = 105950
37 + 105913 = 105950
43 + 105907 = 105950
67 + 105883 = 105950
79 + 105871 = 105950
181 + 105769 = 105950
199 + 105751 = 105950
223 + 105727 = 105950

Showing the first eight; more decompositions exist.
