Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105298, here are decompositions:

29 + 105269 = 105298
47 + 105251 = 105298
59 + 105239 = 105298
71 + 105227 = 105298
131 + 105167 = 105298
191 + 105107 = 105298
227 + 105071 = 105298
311 + 104987 = 105298

Showing the first eight; more decompositions exist.
