Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105256, here are decompositions:

3 + 105253 = 105256
5 + 105251 = 105256
17 + 105239 = 105256
29 + 105227 = 105256
83 + 105173 = 105256
89 + 105167 = 105256
113 + 105143 = 105256
149 + 105107 = 105256

Showing the first eight; more decompositions exist.
