Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105214, here are decompositions:

3 + 105211 = 105214
41 + 105173 = 105214
47 + 105167 = 105214
71 + 105143 = 105214
107 + 105107 = 105214
191 + 105023 = 105214
227 + 104987 = 105214
281 + 104933 = 105214

Showing the first eight; more decompositions exist.
