Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105234, here are decompositions:

5 + 105229 = 105234
7 + 105227 = 105234
23 + 105211 = 105234
61 + 105173 = 105234
67 + 105167 = 105234
97 + 105137 = 105234
127 + 105107 = 105234
137 + 105097 = 105234

Showing the first eight; more decompositions exist.
