Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105310, here are decompositions:

41 + 105269 = 105310
47 + 105263 = 105310
59 + 105251 = 105310
71 + 105239 = 105310
83 + 105227 = 105310
137 + 105173 = 105310
167 + 105143 = 105310
173 + 105137 = 105310

Showing the first eight; more decompositions exist.
