Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87408, here are decompositions:

5 + 87403 = 87408
71 + 87337 = 87408
109 + 87299 = 87408
127 + 87281 = 87408
131 + 87277 = 87408
151 + 87257 = 87408
157 + 87251 = 87408
197 + 87211 = 87408

Showing the first eight; more decompositions exist.
