Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105318, here are decompositions:

41 + 105277 = 105318
67 + 105251 = 105318
79 + 105239 = 105318
89 + 105229 = 105318
107 + 105211 = 105318
151 + 105167 = 105318
181 + 105137 = 105318
211 + 105107 = 105318

Showing the first eight; more decompositions exist.
