Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27886, here are decompositions:

3 + 27883 = 27886
59 + 27827 = 27886
83 + 27803 = 27886
107 + 27779 = 27886
113 + 27773 = 27886
137 + 27749 = 27886
149 + 27737 = 27886
197 + 27689 = 27886

Showing the first eight; more decompositions exist.
