Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105636, here are decompositions:

17 + 105619 = 105636
23 + 105613 = 105636
29 + 105607 = 105636
73 + 105563 = 105636
79 + 105557 = 105636
103 + 105533 = 105636
107 + 105529 = 105636
109 + 105527 = 105636

Showing the first eight; more decompositions exist.
