Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105564, here are decompositions:

7 + 105557 = 105564
23 + 105541 = 105564
31 + 105533 = 105564
37 + 105527 = 105564
47 + 105517 = 105564
61 + 105503 = 105564
73 + 105491 = 105564
97 + 105467 = 105564

Showing the first eight; more decompositions exist.
