Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87328, here are decompositions:

5 + 87323 = 87328
11 + 87317 = 87328
29 + 87299 = 87328
47 + 87281 = 87328
71 + 87257 = 87328
107 + 87221 = 87328
149 + 87179 = 87328
179 + 87149 = 87328

Showing the first eight; more decompositions exist.
