Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105556, here are decompositions:

23 + 105533 = 105556
29 + 105527 = 105556
47 + 105509 = 105556
53 + 105503 = 105556
89 + 105467 = 105556
107 + 105449 = 105556
149 + 105407 = 105556
167 + 105389 = 105556

Showing the first eight; more decompositions exist.
