Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105526, here are decompositions:

17 + 105509 = 105526
23 + 105503 = 105526
59 + 105467 = 105526
89 + 105437 = 105526
137 + 105389 = 105526
167 + 105359 = 105526
257 + 105269 = 105526
263 + 105263 = 105526

Showing the first eight; more decompositions exist.
