Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27916, here are decompositions:

23 + 27893 = 27916
89 + 27827 = 27916
107 + 27809 = 27916
113 + 27803 = 27916
137 + 27779 = 27916
149 + 27767 = 27916
167 + 27749 = 27916
173 + 27743 = 27916

Showing the first eight; more decompositions exist.
