Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105178, here are decompositions:

5 + 105173 = 105178
11 + 105167 = 105178
41 + 105137 = 105178
71 + 105107 = 105178
107 + 105071 = 105178
179 + 104999 = 105178
191 + 104987 = 105178
347 + 104831 = 105178

Showing the first eight; more decompositions exist.
