Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87898, here are decompositions:

11 + 87887 = 87898
17 + 87881 = 87898
29 + 87869 = 87898
101 + 87797 = 87898
131 + 87767 = 87898
179 + 87719 = 87898
197 + 87701 = 87898
227 + 87671 = 87898

Showing the first eight; more decompositions exist.
