Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105858, here are decompositions:

29 + 105829 = 105858
41 + 105817 = 105858
89 + 105769 = 105858
97 + 105761 = 105858
107 + 105751 = 105858
131 + 105727 = 105858
157 + 105701 = 105858
167 + 105691 = 105858

Showing the first eight; more decompositions exist.
