Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105492, here are decompositions:

43 + 105449 = 105492
103 + 105389 = 105492
113 + 105379 = 105492
131 + 105361 = 105492
151 + 105341 = 105492
173 + 105319 = 105492
223 + 105269 = 105492
229 + 105263 = 105492

Showing the first eight; more decompositions exist.
