Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105448, here are decompositions:

11 + 105437 = 105448
41 + 105407 = 105448
47 + 105401 = 105448
59 + 105389 = 105448
89 + 105359 = 105448
107 + 105341 = 105448
179 + 105269 = 105448
197 + 105251 = 105448

Showing the first eight; more decompositions exist.
