Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87916, here are decompositions:

5 + 87911 = 87916
29 + 87887 = 87916
47 + 87869 = 87916
83 + 87833 = 87916
113 + 87803 = 87916
149 + 87767 = 87916
173 + 87743 = 87916
197 + 87719 = 87916

Showing the first eight; more decompositions exist.
