Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105544, here are decompositions:

3 + 105541 = 105544
11 + 105533 = 105544
17 + 105527 = 105544
41 + 105503 = 105544
53 + 105491 = 105544
107 + 105437 = 105544
137 + 105407 = 105544
281 + 105263 = 105544

Showing the first eight; more decompositions exist.
