Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105586, here are decompositions:

23 + 105563 = 105586
29 + 105557 = 105586
53 + 105533 = 105586
59 + 105527 = 105586
83 + 105503 = 105586
137 + 105449 = 105586
149 + 105437 = 105586
179 + 105407 = 105586

Showing the first eight; more decompositions exist.
