Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105786, here are decompositions:

17 + 105769 = 105786
19 + 105767 = 105786
53 + 105733 = 105786
59 + 105727 = 105786
103 + 105683 = 105786
113 + 105673 = 105786
137 + 105649 = 105786
167 + 105619 = 105786

Showing the first eight; more decompositions exist.
