Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105562, here are decompositions:

5 + 105557 = 105562
29 + 105533 = 105562
53 + 105509 = 105562
59 + 105503 = 105562
71 + 105491 = 105562
113 + 105449 = 105562
173 + 105389 = 105562
239 + 105323 = 105562

Showing the first eight; more decompositions exist.
