Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105436, here are decompositions:

29 + 105407 = 105436
47 + 105389 = 105436
113 + 105323 = 105436
167 + 105269 = 105436
173 + 105263 = 105436
197 + 105239 = 105436
263 + 105173 = 105436
269 + 105167 = 105436

Showing the first eight; more decompositions exist.
