Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105262, here are decompositions:

11 + 105251 = 105262
23 + 105239 = 105262
89 + 105173 = 105262
191 + 105071 = 105262
239 + 105023 = 105262
263 + 104999 = 105262
383 + 104879 = 105262
431 + 104831 = 105262

Showing the first eight; more decompositions exist.
