Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115806, here are decompositions:

13 + 115793 = 115806
23 + 115783 = 115806
29 + 115777 = 115806
37 + 115769 = 115806
43 + 115763 = 115806
73 + 115733 = 115806
79 + 115727 = 115806
113 + 115693 = 115806

Showing the first eight; more decompositions exist.
