Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105568, here are decompositions:

5 + 105563 = 105568
11 + 105557 = 105568
41 + 105527 = 105568
59 + 105509 = 105568
101 + 105467 = 105568
131 + 105437 = 105568
167 + 105401 = 105568
179 + 105389 = 105568

Showing the first eight; more decompositions exist.
