Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105340, here are decompositions:

3 + 105337 = 105340
17 + 105323 = 105340
71 + 105269 = 105340
89 + 105251 = 105340
101 + 105239 = 105340
113 + 105227 = 105340
167 + 105173 = 105340
173 + 105167 = 105340

Showing the first eight; more decompositions exist.
