Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105836, here are decompositions:

7 + 105829 = 105836
19 + 105817 = 105836
67 + 105769 = 105836
103 + 105733 = 105836
109 + 105727 = 105836
163 + 105673 = 105836
223 + 105613 = 105836
229 + 105607 = 105836

Showing the first eight; more decompositions exist.
