Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105252, here are decompositions:

13 + 105239 = 105252
23 + 105229 = 105252
41 + 105211 = 105252
53 + 105199 = 105252
79 + 105173 = 105252
109 + 105143 = 105252
181 + 105071 = 105252
229 + 105023 = 105252

Showing the first eight; more decompositions exist.
