Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87076, here are decompositions:

5 + 87071 = 87076
83 + 86993 = 87076
107 + 86969 = 87076
137 + 86939 = 87076
149 + 86927 = 87076
233 + 86843 = 87076
239 + 86837 = 87076
263 + 86813 = 87076

Showing the first eight; more decompositions exist.
