Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87994, here are decompositions:

3 + 87991 = 87994
17 + 87977 = 87994
83 + 87911 = 87994
107 + 87887 = 87994
113 + 87881 = 87994
191 + 87803 = 87994
197 + 87797 = 87994
227 + 87767 = 87994

Showing the first eight; more decompositions exist.
