Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27806, here are decompositions:

3 + 27803 = 27806
7 + 27799 = 27806
13 + 27793 = 27806
43 + 27763 = 27806
67 + 27739 = 27806
73 + 27733 = 27806
109 + 27697 = 27806
223 + 27583 = 27806

Showing the first eight; more decompositions exist.
