Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105574, here are decompositions:

11 + 105563 = 105574
17 + 105557 = 105574
41 + 105533 = 105574
47 + 105527 = 105574
71 + 105503 = 105574
83 + 105491 = 105574
107 + 105467 = 105574
137 + 105437 = 105574

Showing the first eight; more decompositions exist.
