Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105828, here are decompositions:

11 + 105817 = 105828
59 + 105769 = 105828
61 + 105767 = 105828
67 + 105761 = 105828
101 + 105727 = 105828
127 + 105701 = 105828
137 + 105691 = 105828
179 + 105649 = 105828

Showing the first eight; more decompositions exist.
