Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105810, here are decompositions:

41 + 105769 = 105810
43 + 105767 = 105810
59 + 105751 = 105810
83 + 105727 = 105810
109 + 105701 = 105810
127 + 105683 = 105810
137 + 105673 = 105810
157 + 105653 = 105810

Showing the first eight; more decompositions exist.
