Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10806, here are decompositions:

7 + 10799 = 10806
17 + 10789 = 10806
53 + 10753 = 10806
67 + 10739 = 10806
73 + 10733 = 10806
83 + 10723 = 10806
97 + 10709 = 10806
139 + 10667 = 10806

Showing the first eight; more decompositions exist.
