Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105306, here are decompositions:

29 + 105277 = 105306
37 + 105269 = 105306
43 + 105263 = 105306
53 + 105253 = 105306
67 + 105239 = 105306
79 + 105227 = 105306
107 + 105199 = 105306
139 + 105167 = 105306

Showing the first eight; more decompositions exist.
